    Informatics colloquium 12. 12. Troubles with RSA cryptographic keypair generation

    Informatics colloquium 12. 12. 2017, 14:00 lecture hall D2 RNDr. Petr Švenda, Ph.D., FI MU Troubles with RSA cryptographic keypair generation Abstract: The talk will cover our recent work [1] which resulted in the discovery of an algorithmic flaw in the construction of primes for RSA key generation in a widely-used library of a major manufacturer of cryptographic hardware. The primes generated by the library suffer from an entropy loss so severe, that practical factorization of commonly used key lengths up to 2048 bits is possible. Our method based on an extension of Coppersmith’s factorization attack requires no additional information except for the value of the public modulus and does not depend on a weak or a faulty random number generator. The library in question is found in NIST FIPS 140-2 and CC EAL 5+ certified devices used for a wide range of real-world applications, including citizens identity cards, Trusted Platform Modules, secure email, and tokens for authentication or software signing. The findings directly resulted in the revocation of millions of certificates in Estonia, Slovakia, Spain and other countries and major security update rolled by Microsoft, Google, HP, Lenovo, and others. The talk will discuss how the vulnerability was found, what was the root cause for its existence, our experience from the responsible disclosure process and the options how to systematically prevent such a large-scale failure in the future.

    Informatics colloquium 19. 12. Navigating the Space of Visualizations

    Informatics colloquium 19. 12. 2017, 14:00 lecture hall D2 prof. Stefan Bruckner, Faculty of Mathematics and Natural Sciences, University of Bergen Navigating the Space of Visualizations Anstract: Considering the vast amounts of data involved in many scientific disciplines and industrial applications, it is essential to provide effective and efficient means for forming a mental model of the underlying phenomenon. The term "visualization" refers to the process of extracting meaningful information from data and constructing a visual representation of this information. While the concept of using images to communicate complex phenomena of course predates the development of digital technology by millennia, over the past decades the field of visualization has firmly established itself as an important and constantly expanding discipline within computer science. Computer-based Visualization seeks to provide interactive graphical data representations, taking advantage of the extraordinary capability of the human brain to process visual information. Advanced visualization methods now play an an important role in the exploration, analysis, and presentation of data in many fields such as medicine, biology, geology, or engineering. This development, however, has also lead to the fact that there is now a vast number of often very specialized techniques to visualize different types of data tailored towards specific tasks. For non-experts it becomes non-trivial to choose appropriate methods that will provide the optimal answers to their questions. In this talk, I will discuss previous and ongoing research on how we can explore and navigate the space of visualizations itself. By consider the interplay between data, visualization algorithms, their parameters, perception, and cognition as a complex phenomenon that deserves study in its own right, we are making progress in providing goal-oriented interfaces for visual analysis. For instance, we can make the modification of input parameters of visualization algorithms more intuitive by normalizing their perceived effects over the entire value range, and provide visual guidance about their influence. Furthermore, by incorporating additional knowledge into the visualization process, we can infer information about the goals of a user, and develop smarter systems that automatically suggest appropriate visualization techniques. This line of investigation leads us along the path towards a new type of visual data science, where automated data analysis approaches such as deep learning are tightly coupled with interactive visualization techniques to exploit their complementary advantages for knowledge discovery in data-driven science. Short biography: Stefan Bruckner is professor in visualization at the Department of Informatics of the University of Bergen, Norway. Prior to his appointment in Bergen, he was an assistant professor at the TU Wien, Austria where he also received his habilitation (2012) and PhD (2008). His research focuses on interactive visualization and he has made important contributions to several areas such as illustrative methods, parameter space exploration, feature detection, and knowledge-based interfaces. Prof. Bruckner has successfully led several research projects including industry collaborations with partners such as AGFA HealthCare and GE Healthcare. His results were published in the premier venues for visualization research and have to date received 8 best paper awards and honorable mentions at international events. He won the Karl-Heinz-Höhne Award for Medical Visualization and received the prestigious Eurographics Young Researcher Award. As an active member of the international scientific community, Prof. Bruckner regularly serves on the program committees of the leading conferences in visualization and computer graphics. He was program co-chair of EuroVis, PacificVis, VCBM, and the Eurographics Medical Prize, and currently serves on the editorial board of Computers & Graphics. He is a member of the IEEE Computer Society, ACM SIGGRAPH, and Eurographics.
