Verena Biener (FH Coburg)
Mixed Reality for Mobile Knowladge Work

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

Abstract:
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.

Bio:
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.

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

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.

Visualizing Graph Structures

July 05^th, 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 01^st, 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.

Carsten Baum:
Efficient Designated-Verifier Zero-Knowledge and Cheese Puns

May 19^th, 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.

A formal analysis of boomerang probabilities

April 29^th, 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 09^th, 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 19^th, 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.
