Efficient and Generic Microarchitectural Hash-Function Recovery

February 12th, 2024 | 3 - 4 pm
Place: ifeg042
Organizer: IAIK
Website of Lukas Gerlach

Lukas Gerlach is a PhD student at CISPA Helmholtz Center for Information Security microarchitecture and systems security at the reasearch group of Michael Schwarz. He received his Bachelor's degree in Computer Science from Saarland University. Lukas work focuses on various topics ranging from novel architectures such as RISC-V over automated reverse engineering of CPUs to Rowhammer attacks. He is a passionate CTF player focussing on exploition and cryptography for the saarsec team.

Modern CPUs use a variety of undocumented microarchitectural hash functions to efficiently distribute data within microarchitectural structures such as caches. A wellknown function is the cache slice function that distributes cache lines to the slice of the last-level cache. Knowing these functions considerally improves microarchitectural attacks, such as Prime+Probe or Rowhammer. However, while several such linear functions have been reverse-engineered, there is no generic and automated approach for reverse-engineering nonlinear functions, which are common with modern CPUs.

In this presentation, we introduce a generic approach for automatically reverse-engineering a wide range of microarchtictural hash functions. Our approach combines techniques initially used for logic-gate minimization and from computer algebra to infer the hash functions based on input-output pairs observed via side channels.

With our framework, we infer 3 previously unknown non-linear hash functions on both AMD and Intel CPUs, including the new Alder Lake hybrid-CPU architecture. We verify our approach by reproducing knwon hash functions and evaluating side-channel attacks that rely on these functions, resulting in success rates above 97,65%. We stress the need to design such functions with both performance and security in mind and discuss alternative designs that can be used in the future CPUs.

New Techniques for Efficient Isogeny-based Encryption Protocols

February 8th, 2024 | 1:30 - 2:30 pm
Place: IFEG042

Isogeny-based cryptography is known for its low bandwidth requiremenets, which often come at the cost of slower computations. SIDH, one of the most well-known isogeny-based key exchanges, and the only one submitted to the NIST standardisation process, was broken in 2022 in a series of three breakthrough papers. The attack relies on isogenies between abelian varieties (a generalisation of elliptic curves to higher dimensions), and it leads to a complete key recovery within seconds.

In this talk, we discuss two approaches to obtaining secure protocols that could, eventually, replace SIDH. The first approach involves modifying the SIDH protocol to includesimple but effective countermeasures against all known attacks. The technique is based on restricting the set of potential isogenies, so that less information about the secret isogeny (in the form of torsion images) need to be revealed.

The second approach is based on the development os a new PKE, which we call FESTA. The attacks on SIDH rely on higher-dimesional isogenies to make some computations, previously believed to be hard, extremly efficient. In FESTA, we use the same techniques constructively: we build a trapdoor function where the inversion operation consists of recovering an SIDH secret key. From the trapdoor, it is then simple to obtain an IND-CCA PKE through standard transformations.

Andrea Basso is a postdoctoral researcher at the University of Bristol, where he focusses on developing new isogeny-based protocols, with a particular interest in advanced functionalities such a non-interactive key exchanges and obvious pseudorandom functions. He received his PhD from the University of Birmingham, and he will soon join IBM Research Zurich as a postdoctoral researcher.

"Recent Advances in Cryptography and Privacy Engineering"

January 15th, 2024, | 4 pm
Place: SR DHEG045 (Data House)
Organizer: Institute IAIK

Secure two-party computation allows two parties to securely compute a function on their respective private inputs. It allows to preserve privacy in applications that involve a client and a single server, and in settings where private data is outsourced to two non-colluding servers. In this talk, I will give an overview on recent advances in the area of secure two-party computation. In particular, I will focus on the setting with semi-honest parties, which allows to construct the most efficient protocols. I will summarize three recent research results from the ENCRYPTO group: First, circuit synthesis and secure evaluation of circuits should be considered together to not leak private information when evaluating malformed circuits with popular instantiations of Yao's garbled circuits protocol (JoC'23). In the area of secret-sharing based protocols, ABY2.0 (USENIX Security’21) allows highly efficient secure evaluation of Boolean circuits with multi-input AND gates and vector products, and FLUTE (IEEE S&P’23) extends these results to multi-input lookup tables. Among many other applications, these protocols substantially improve efficiency of privacy-preserving machine learning.
Short Bio:
Thomas Schneider is full professor for Cryptography and Privacy Engineering in the Department of Computer Science at Technical University of Darmstadt, Germany. Before, he was independent research group leader at TU Darmstadt (2012-2018), did a PhD in IT Security at Ruhr-University Bochum (2008- 2011), and wrote his Master thesis during a research internship at Nokia Bell Labs, NJ, USA (2007). His research focuses on privacy, cryptographic protocols, applied cryptography, and computer security. He heads the Cryptography and Privacy Engineering Group (ENCRYPTO), whose mission is to demonstrate that privacy can be efficiently protected in real-world applications. For this, his group combines applied cryptography and algorithm engineering to develop cryptographic protocols and tools for protecting sensitive data and algorithms. For his research on cryptography and privacy engineering, he was awarded with an ERC Starting Grant 2019 and an ERC Consolidator Grant 2023.

"Imitation Learning and Value Alignment Under Mismatch and Constraints"

December 12th, 2023 | 12 pm
Place: IFEG042, Inffeldgasse 16a
Organizer: Institute IAIK

Reinforcement learning has been successfully used for training AI agents when given clearly defined reward signals. However, reinforcement learning can suffer from high sample complexity and is challenging to use in settings in which the reward signal is hard to specify, e.g., for training personal agents that should maximize a human-defined reward function. We investigate imitation learning and reinforcement learning from human feedback which allows us to avoid the specification of a reward function and can drastically reduce sample complexity. Inspired by real-world applications, we particularly study settings in which there is a mismatch between the human providing demonstrations or feedback and the learning AI agent, e.g., in terms of observations, capabilities, or constraints. Our insights emphasize the need for adaptation of the human and the AI agent to achieve the best alignment regarding the human's goals. Furthermore, we propose practical algorithms to perform this adaptation and sample efficient approaches for learning about rewards and constraints.

"Visualization Recommendation Demystified: Navigating the Multiverse of Data Visualization Guidance"

November 24th, 2024 | 11 am
Place: SR CGV, Inffeldgasse 16c/II
Organizer: Institute CGV

Visualization Recommendation (VisRec) has emerged as a prominent and dynamic area of research, drawing substantial attention from scholars and practitioners alike. While recent studies have prominently explored the application of machine learning and artificial intelligence to VisRec, it is imperative to recognize that VisRec encompasses a multifaceted challenge. Beyond the 'how' it can be applied, it necessitates an understanding of the fundamental 'what' and 'why' behind its application. This talk seeks to provide a holistic perspective on visualization recommendation and automated decision-making. We integrate concepts from diverse problem domains, including visual parameter space exploration, visual guidance, established decision-making theories, and other relevant fields. By amalgamating these diverse streams of knowledge, our presentation will illustrate how Human-Computer Interaction can be conceptualized as a two-way communication process according to Shannon's communication model. We use this insight as a basis to explore how (semi-)automated knowledge assistance processes emulate human communication behaviors. Our findings will shed light on the practicality and simplicity of VisRec. We will demonstrate that, in many instances, VisRec can be applied in an uncomplicated manner by leveraging existing knowledge, challenging the notion of complexity often associated with it. Ultimately, we will encourage the audience to view the entire VisRec process from a multiverse perspective, fostering a deeper understanding of its potential and practical applicability.

"Propagation of Subspaces in Primitives with Monomial Sboxes"

October 30th, 2023 | 4 pm
Place: IFEG042

Motivated by progress in the field of zero-knowledge proofs, so-called Arithmetization-Oriented (AO) symmetric primitives have started to appear in the literature, such as MiMC, Poseidon or Rescue.  Due to the design constraints implied by this setting, these algorithms are defined using simple operations over large (possibly prime) fields. In particular, many rely on simple low-degree monomials for their non-linear layers.
 In this work, we show that the structure of the material injected in each round (be it subkeys in a block cipher or round constants in a public permutation) could allow a specific pattern, whereby a well-defined affine space is mapped to another by the round function, and then to another, etc. Such chains of one-dimensional subspaces always exist over 2 rounds, and they can be extended to an arbitrary number of rounds provided that the round-constants are well chosen.
As a consequence, for several ciphers like Rescue, or a variant of AES with a monomial Sbox, there exist some round-key sequences for which the cipher has an abnormally high differential uniformity, exceeding the size of the Sbox alphabet.
Well-known security arguments, in particular based on the wide trail strategy, have been reused in the AO setting by many designers.
Unfortunately, our results show their limits. To illustrate this, we present two new primitives (a tweakable block cipher and a permutation-based hash function)  that are built using state-of-the-art security arguments, but which are actually deeply flawed.

Vladimir Bozovic and Veljko Milutinov
from the University of Montenegro visit TU Graz

November 9th, 2024, | 2:15 pm
Place: HS FSI 1 "Magna Steyr Hörsaal" (FSEG054), Inffeldgasse 11
Organizer: Institute ISDS

Vladimir Bozovic, Rector of the University of Montenegro (UoM)
Vladimir Bozovic is the Rector of the UoM, a matematician with Ph.D.  from the Florida Atlantic University in Boca Raton, Florida, USA. He has received some of the greatests local and international awards for his research results.

His presentation gives an overview of the University of Montenegro (UoM) historical perspectives and current missions. UoM is the only state-owned university of Montenegro and unifies all aspects of interest for the highest education: From social studies and humanities, over mathematics and sciences, all the way to engineering and informatics. In its social and cultural missions, it is dedicated to modern studies that both widen the horisons of students and deepen their professional knowledge (e.g., in the past few years, the UoM or the related manifestations were visited by 4 different Nobel Laureates who shared their wisdom with the students, of which two delivered repeated lectures years appart: Dan Shechtman and Kostya Novoselov). In its engineering and scientific missions, especially at its international PhD program, it enrolls students from a number of countries in the region, and some from EU countries, too, due to its constant struggle for the highest levels of professional development (e.g., in the domain of VLSI processor-on-a-chip-design and related AI problems: two gigantic USA companies are leading the world markets, and at both companies, the current Vice Presidents are an alumnis and a former director of computing at UoM and an expert of Montenegrin descent: Ranko Scepanovic and Milivoje Aleksic. Some of the past or current students at TU Graz do come from Montenegro or are from the Montenegrin diaspora.

Veljko Milutinovic, Adjunct Professor of the University of Montenegro
He received his PhD from the University of Belgrade, has been on faculty positions the USA, at Purdue University and Indiana University, and is credited for the DARPAs first GaAs (Gallium Arsendie) microprocessor at 200MHz (about a decade before mainstream)  and the DARPAs first GaAs Systolic Array with 4096 CPUs. We was also long time member oft he board of Academia Europaea)

His presentation, possibly followed by an on-site or an on-line mini-course or a full-blown course on DataFlow Programming, analyses the essence of DataFlow SuperComputing, defines its advantages and sheds light on the related programming model. The stress is on issues of interest for General Engineering. The DataFlow paradigm, compared to the ControlFlow paradigm, offers: (a) Speedups of at least 10x to 100x and sometimes much more (depends on the algorithmic characteristics of the most essential loops and the spatial/temporal characteristics of the Big Data Streem, etc.), (b) Potentials for a better precision (depends on the characteristics of the optimizing compiler and the operating system, etc.), (c) Power reduction of at least 10x (depends on the clock speed and the internal architecture, etc.), and (d) Size reduction of well over 10x (depends on the chip implementation and the packaging technology, etc.). The bigger the data, and the higher the reusability of individual data items (which is typical of ML), the higher the benefits of the dataflow paradigm over the control flow paradigm. However, the programming paradigm is different, and has to be mastered. The ongoing research of the speaker has been highly influenced by four different Nobel Laureates: (a) from Richard Feynman it has been learned that future computing paradigms will be successful only if the amount of data communications is minimized; (b) from Ilya Prigogine it has been learned that the entropy of a computing system could be minimized if spatial and temporal data get decoupled; (c) from Daniel Kahneman it has been learned that the system software should offer options related to approximate computing; and (d) from Tim Hunt it has been learned that the system software should be able to trade latency for precision.

"Affordable open hardware, open-source mobile mapping system for all scenarios"

October 12th, 2023 | 9 am
Place: Seminarrum IST

This talk concerns recent status of an affordable open hardware, open-source mobile mapping system for mobile mapping applications. Recent experiments show that it can be efficiently used in many scenarios such as culture heritage, urban search and rescue, urban mapping, AGV (automated Guided Vehicle) navigation etc. The main idea was to develop portable mobile mapping system that can be handheld, can be mounted on the bicycle, slaw motion vehicle etc. It provides trajectory and 3D map (point cloud) of traversed environment. The software stack is composed of lidar odometry and loop closure.  It is possible to align multiple sessions into one reference frame. The project of city-level map building will be elaborated. Recently, challenging Urban Search and Rescue scenarios were performed, thus results with K9 will be shown. The movement of the dog is challenging and the expectations of the end users are far away from technology advancement, thus future research is addressed.

September 19th, 2023 | 10 am
Place: IST Seminarraum (IC02062)

Short abstract:
Machine learning is a popular tool for building state of the art software systems. It is more and more used also in safety critical areas. This demands for verification techniques ensuring the safety and security of machine learning based solutions. However, in this presentation, we argue that the popularity of machine learning comes from the fact that no formal specification exists which renders traditional verification in appropriate. Instead, validation is typically demanded and we present a recent technique that validates certain correctness properties for an underlying recurrent neural network: Property-directed verification of Recurrent Neural Networks.

Martin Leucker is currently a professor at the University of Lübeck, Germany heading the Institute of Software Engineering and Programming Languages. He obtained his Ph. D. at the RWTH Aachen, Germany and afterwards, he worked as a Postdoc at the University of Philadelphia, USA and at the Uppsala University, Sweden. He pursued his habilitation at the TU München, Germany. He is the author of more than 100 peer reviewed conference and journal papers ranging over software engineering, formal methods and theoretical computer science.

Formal Hardware/Software Modeling for Timing Properties: from Safety to Security

July 11th, 2023, | 10 am
Place: IFEG042

Short abstract:
The emergence of open hardware initiatives, for instance, based on the RISC-V ISA, exposes more easily the exact behavior of hardware designs. They can then be analyzed and combined with application-level semantics to formally verify complex safety (and security) properties at the system level. In this talk, we first present an overview of the LEAF approach for verifying such timing-related properties. Then, we focus on the required formal model tailored to a specific property: the detection of Timing Anomalies (TA) within pipelines of processors. A TA is a counterintuitive timing behavior that can threaten Worst-Case Execution Time (WCET) analyses. We also report ongoing work to generate such pipeline formal models from RISC-V processors described in Chisel/FIRRTL. Finally, we conclude on current extensions to apply the LEAF approach to safety properties.

Dr. Mathieu Jan obtained his engineering diploma in 2003 and got a Ph.D. in 2006 on data management for grid architectures from Univ. of Rennes 1 in an INRIA laboratory. He joined CEA LIST in 2007 as a full-time researcher. Since then, his main research interests are embedded systems and real-time systems. Senior expert at CEA LIST since 2014, he obtained a "Habilitation à Diriger des Recherches" (HDR) in 2016, and is a CEA Research Director since 2021. He spent the whole year 2019 as visiting scholar at the University of California, Berkeley (UCB) in the group of Prof. Edward Lee. Since 2020, Mathieu focuses on the hardware/software formal verification of embedded systems and is the Ph.D. director of several Ph.D. students in this area.

Pulmonary hypertension: estrogens and obesity

July 27th, 2023, | 3 pm
Place: BMT03094

Short abstract:
Pulmonary arterial hypertension (PAH) is most frequently observed in women. Sex hormones likely play a role in the development of PAH and we will discuss the roles of estrogens and estrogen metabolites. These are elevated in both male and female patients. Estrogen and 16-hydroxyestrogen metabolites have pathogenic effects in the lung, inducing pulmonary vascular remodelling and this may involve oxidative stress. Many PAH patients are obese and evidence suggests this impacts significantly on the pathogenesis of PAH partially through increased estrogen synthesisis.

Mandy obtained her PhD in Pharmacology from the University of Edinburgh in 1985 and then spend a year in the USA and three years in Cambridge before moving to The University of Glasgow in 1989. Mandy joined The University of Strathclyde in 2019. Her research has focused on the role of serotonin in the development of pulmonary arterial hypertension (PAH). As more women get PAH than men, more recently her work has focused on sex effects and oestrogen metabolism in PAH. She has a BHF programme grant and won the 2017 Reynold Spector Award for Clinical Pharmacology from the American Society for Pharmacology and Experimental Therapeutics (ASPET). Other research awards include a Royal Society Wolfson Research Merit Award and a Royal Society Leverhulme Trust Senior Research Fellowship. She sits n numerous grant funding panels and is a trustee of The Academy of Medical Sciences and The Glasgow Children’s Hospital Charity.

Jean-Max Dutertre: "Review of laser and EM fault injection attacks into microcontrollers"

July 5th, 2023, | 2 pm
Place: IFEG042

Abstract: Microcontrollers storing valuable data or using security functions are vulnerable to fault injection attacks. Among the various types of faults, instruction skips induced at runtime proved to be effective against identification routines or encryption algorithms. Until recently, most research papers assessed a fault model that consists in a single instruction skip, i.e. the ability to prevent one chosen instruction in a program from being executed. This seminar reports experimental results that extend the complexity and versatility of the instruction-skip fault model. It shows how using laser or EM fault injection makes it possible to induce several consecutive instructions skips or to skip instructions from different parts of a program. It focuses on results obtained on custom test circuits and general purpose microcontrollers at different technology nodes. An analysis of the involved injection mechanisms is also provided.

Short bio: Prof. Jean-Max Dutertre received the M.S. and Ph. D. degrees in microelectronics from the University of Science of Montpellier, France, in 1998 and 2002, respectively. He is head of the Secured Architectures and Systems (SAS) research department of Mines Saint-Etienne from Institut Mines-Télécom, which is part of a joint R&D team with the CEA Leti. His research interests are with hardware attacks techniques and the design of the related counter-measures (either hardware or software). He is studying fault injection attacks of secure integrated circuits for 15 years

Mixed Reality for Mobile Knowledge Work

June 2nd, 2023 | 11 am
Place: Franz Leberl Seminarraum

Not least due to the Corona pandemic, mobile working is very widespread, especially among knowledge workers. However, in the home office, on public transportation, or in waiting rooms, the work environments and available mobile devices are often not optimal. Mixed reality has the potential to solve some such problems, for example by displaying multiple virtual screens of variable size that can make working easier.
Similarly, the work environment can be customized to the users preferences. In the course of my PhD, I am exploring the practicality of using virtual work environments over longer periods of time and in everyday situations. In addition, I evaluated different input and output modalities including the use of traditional devices such as mouse, keyboard and tablet combined with the possibilities offered by Mixed Reality, such as depth perception or eye-tracking.

Verena Biener is a Ph.D. candidate in computer science at Coburg University in cooperation with the University of Bayreuth. She is advised by Professor Dr. Jens Grubert and Professor Dr. Jörg Müller. Her research is about using mixed reality for knowledge worker tasks in mobile settings. She evaluates different interaction techniques using common devices like touch screens as well as eye-tracking or spatially tracked devices, and she is also interested in the effects of using mixed reality for knowledge work in ecologically valid settings. Verena Biener received her bachelor’s degree in computer science from University of Tübingen, Germany and completed her M.S in computer science at University of Stuttgart, Germany.

"The titel of this talk is the motto of the Intelligent and Interactive Systems group at the Universitiy of Innsbruck. Our long-term objective is to improve abstraction, robustness, and ultimately explainability of robot perception and action. Motivated by shortcomings of current machine-learning methods, I will discuss examples of our recent work on learning visual relational concepts, extrapolation of learned movements beyond the training distribution, and learning of symbolic concepts and ruels from sensorimotor experience. As an added bonus, I will show how to train neutral networks of a thousand layers without skip connections, batch normalization, propout, or any other architectural tweaks, using our so-called batch-entropy regularization."

Prof. Ruzica Piskac - Yale: Privacy-preserving Automated Reasoning

December 22 | 2 pm

Place: IFEG042 Inffeldgasse 16a, EG

Bugs in software and hardware can often to catastrophic consequences. There are various ways to improve software quality, formal verification being the most rigorous of all. In formal verification, the goal is to translate programs into formulas, and then automatically prove the correctness of these formulas. Formal methods offer a vast collection of techniques to analyze and verify these systems mathematically to ensure the correctness, robustness, and safety of software and hardware systems against a specification. Despite the significant success of formal method techniques, privacy requirements are not considered in their design.

In the last two decades, we have witnessed fascinating progress in the area of automated reasoning. Modern automated reasoning tools are now applied daily to tasks in program analysis, software engineering, hardware verification, and various other domains. The efficacy of such tools allows their application to even large-scale industrial codebases.

In this talk, we will present our work on adding a privacy-aware perspective to automated reasoning. When using automated reasoning tools, the implicit requirement is that the formula to be proved is public. We propose the concept of privacy-preserving formal reasoning. In our recent work on a zero-knowledge protocol for proving the unsatisfiability of Boolean formulas in propositional logic, we developed a highly efficient protocol for knowledge of a resolution proof of unsatisfiability. We encoded verification of the resolution proof using polynomial equivalence checking, which enabled us to use fast ZKP protocols for polynomial satisfiability.

Neural Termination Analysis

September 28th, 2022, | 9:00 am
Place: Inffeldgasse 16a, IFEG042

We introduce a novel approach to the automated termination analysis of computer programs: we train neural networks to behave as ranking functions. Ranking functions map program states to values that are bounded from below and decrease as the program runs. The existence of a ranking function proves that the program terminates. We learn ranking functions from execution traces by training a neural network so that its output decreases along the sampled executions; then, we use symbolic reasoning to formally verify that it generalises to all possible executions. We demonstrate that, thanks to the ability of neural networks to represent highly complex functions, our method succeeds over programs that are beyond the reach of state-of-the-art tools. This includes programs that use loop guards with disjunctions and programs that exhibit nonlinear behaviour.

In her Master thesis “Frauen@TUG – Do IT” Anna Napetschnig has developed a catalog of measures for the qualitative and quantitative improvement of the situation of female computer science students at the TU Graz. The first part of the thesis is an inventory of projects for the promotion of young female computer science students at Graz University of Technology and at comparable universities. The second part consists of qualitative and quantitative surveys of female TU Graz students on these measures. This results in a catalog of measures with individual recommendations for the TU Graz, which have the potential to increase the proportion of female computer science students and to reduce the drop out.

Visualizing Graph Structures

July 05th, 2022, | 1:00 pm
Place: SR CGV

Inevitably, the projection of most graph structures on two-dimensional screens will create errors and therefore visually wrong impressions. In the past, two types of methods have been developed to minimize projection errors and distribute them in a visually pleasing way. The first group of methods, force-directed layouts, interpret the links of a graph as physical springs, while stress-based methods minimize an energy function, which aims to map graph distances faithfully. A unified description of both method types allows to create optimal parameters for both and even to specify new, better methods for most graphs. The addition of vector-based constraints enable systems to render graphs with different layouts and under varying perspectives. Finally, I will show that deviating from all kinds of physical metaphors is a good idea to create even better projection methods.

DevOps Theory vs. Practice

June 01st, 2022, | 12:01 pm
Place: WebEx

There are a lot of simplified representations of DevOps, but practice shows that it is more difficult than that. Many tools need to mesh like gears, and humans have to interact with each other to provide functional applications to end users. This talk will show how DevOps can be implemented in a way that serves all stakeholders. Automation techniques like Continuous Integration and Continuous Delivery will be introduced, and it will be described how test automatization can be used to reach the goal of a full Continuous Deployment process.

Presenter: Alexander Kalchauer - Alexander is an alumni of TU Graz in Software Engineering and Management and also an alumni of the Catrobat project :logo:. He has worked for 8 years as a technical lead for Dr. Nagler & Company Austria. During this time he was a member of several large project teams working on market data, financial trade data and risk management for several national and international clients. Currently he is implementing DevOps processes for a large German investment company.

Efficient Designated-Verifier Zero-Knowledge and Cheese Puns

May 19th, 2022, | 4:00 pm
Place: IFEG042


Zero knowledge proofs are an important building block in many cryptographic applications. Unfortunately, when the proof statements become very large, existing zero-knowledge proof systems easily reach their limits: either the computational overhead, the memory footprint, or the required bandwidth exceed levels that would be tolerable in practice.

In this talk, I present a designated-verifier zero-knowledge proof system for boolean and arithmetic circuits, called Mac’n’Cheese (CRYPTO 2021), with a focus on supporting large circuits. The work follows the commit-and-prove paradigm instantiated using information-theoretic MACs based on vector oblivious linear evaluation to achieve high efficiency. It additionally allows to optimize disjunctions, with a general OR transformation for proving the disjunction of m
statements that has communication complexity proportional to the longest statement. These disjunctions can further be nested, allowing efficient proofs about complex statements with many levels of disjunctions. Mac’n’Cheese can be made non-interactive (after a preprocessing phase) using the Fiat-Shamir transform.

Additionally, I will present two other recent results which built upon the Mac’n’Cheese proof system. First, I will discuss how to efficiently convert between different proof systems with an approach called Appenzeller2Brie (CCS 2021). Moreover, I will show that a protocol similar to Mac’n’Cheese can be constructed to permit proofs over rings modulo 2^k. This protocol, called QuarkSilver, is the first such protocol to natively work over these rings.

April 29th, 2022, | 9:30 am
Place: IFEG042


In the past 20 years since their conception, boomerang attacks have become an important tool in the cryptanalysis of block ciphers. In the classical estimate of their success probability, assumptions are made about the independence of the underlying differential trails that are not well-founded. We underline the problems inherent in these independence assumptions by using them to prove that for any boomerang there exists a differential trail over the entire cipher with a higher probability than the boomerang.
We further provide a framework which allows us to formulate and prove rigorous statements about the probabilities involved in boomerang attacks without relying on independence assumptions of the trails.

The Formalization and Representation of Expert Knowledge with Visual Analytics to Improve Product Quality in Serial Manufacturing Processes

December 09th, 2021 | 11:00 pm |  online

Advances in new technologies, such as the Internet of Things (IoT) and big data analytics are enabling a new generation of smart manufacturing processes. These technologies allow the efficient tracking of the quality of produced parts along every step in the manufacturing process.
Here, sophisticated measurement equipment forms interconnected IoT networks, where the “smartness” level depends to great extent on how organizations can leverage data-driven approaches to create value of resulting big datasets and to support human experts with their high-cognition analysis tasks. In this regard, Visual Analytics (VA) can help to integrate human experts into the visual exploration of IoT data by augmenting analytical reasoning capabilities together with model-supported and custom-designed visualization interfaces. Thus, in this thesis, we analyze the role of VA in serial manufacturing processes. Specifically, we aim to examine how such visualization approaches can be used to formalize and represent expert knowledge to make it readily accessible for the development of data-driven approaches, which show great potential in improving serial manufacturing processes. In doing so, we present results from four design study projects in collaboration with a German manufacturer of electric vehicles. Our results indicate that VA shows great potential in augmenting human analytical reasoning processes of knowledge-intensive tasks. Furthermore, we outline how features, models, and especially labels can be leveraged by organizations as explicit knowledge products to be shared among organizational members and leveraged to engage in sophisticated data-driven approaches.

Daniele Venturi introduce a new form of encryption that we name matchmaking encryption (ME). Using ME, sender S and receiver R (each with its own attributes) can both specify policies the other party must satisfy in order for the message to be revealed. The main security guarantee is that of privacy-preserving policy matching: During decryption nothing is leaked beyond the fact that a match occurred/did not occur. ME opens up new ways of secretly communicating, and enables several new applications where both participants can specify fine-grained access policies to encrypted data. For instance, in social matchmaking, S can encrypt a file containing his/her personal details and specify a policy so that the file can be decrypted only by his/her ideal partner. On the other end, a receiver R will be able to decrypt the file only if S corresponds to his/her ideal partner defined through a policy. On the theoretical side, we define security for ME, as well as provide generic frameworks for constructing ME from functional encryption. These constructions need to face the technical challenge of simultaneously checking the policies chosen by S and R, to avoid any leakage. On the practical side, we construct an efficient identity-based scheme for equality policies, with provable security in the random oracle model under the standard BDH assumption. We implement and evaluate our scheme and provide experimental evidence that our construction is practical. We also apply identity-based ME to a concrete use case, in particular for creating an anonymous bulletin board over a Tor network.

Computer science education in Bavaria: reacting to the challenges of digitization

When: October 19th, 2021 from 17:00 - 18:00
Where: HS BE01, Steyrergasse 30, Ground Floor // Webex
Registration required!

The unstoppable digitization of all areas of life is changing our society sustainably and dramatically. School education must respond to this appropriately, i.e., on a broad front. This requires a carefully planned, long-term, evidence-based overall strategy designed for sustainability, which must touch (almost) all areas of school activity. In line with this universality of demands, an enormous diversity of terms used for informatics education is evident worldwide. We have identified over 40 relevant terms for this purpose. Equally diverse are the teaching contents offered in this area. The identification of competencies to be learned by students poses particular difficulties. There is very little preliminary research on this to date.
To master digital systems, our students need solid knowledge of their technical functioning and logical structure as well as competencies suitable for everyday use to apply digital tools effectively and efficiently. This foundation can only be learned in a dedicated subject of computer science. But all other school subjects must also respond to the challenges of digitization by adapting their learning objectives, learning methods and the media used accordingly. However, it is not easy to make such changes to an existing school system while it is still in operation. The greatest challenge here is the restructuring of pre- and in-service teacher education, both in computer science and in the didactics of all other subjects.
The German State of Bavaria already reacted to this challenge in 2000 with the introduction of a compulsory subject in computer science at its Gymnasien and Realschulen, which was significantly developed designed and supported by the author, i.a. in teacher education, curriculum work, and by writing textbooks. This was followed in 2019 by another major offensive by the state government, in which the existing compulsory subject of computer science was further expanded as well as newly introduced at main schools.
In this presentation, the basic concept of this subject will be presented, as well as some supporting activities such as teacher training. However, in the course of these activities, some persistent obstacles have also emerged that are very difficult to remove, Above all, the low enrollments in teacher training programs for computer science, as can be observed in almost all concerned countries. One possible reason for this could be found in the contradictory personal requirements of a teaching degree on the one hand and a computer science degree on the other.
