Maßnahmen zur Erhöhung des Frauenanteils an der Fakultät CSBME

July 13^th, 2022, | 4-6 pm
Place: HS FSI 2 - Inffeldgasse 11
in German

Anna Napetschnig presents her Master Thesis “Frauen@TUG – Do IT! Successful approaches to improve the qualitative and quantitative situation of female students of computer science at Graz University of Technology” and we will discuss her recommendations.
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.

She won the Mind the Gap Diversity Award 2021.

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.
