CryptoLUX is a cryptology research group within the Computer Science and Communications (CSC) research unit of the University of Luxembourg. Professor Alex Biryukov is head of CryptoLUX and leads a team consisting of two permanent staff members (Johann Großschädl, Yann Le Corre), three postdoctoral researchers, and about half a dozen Ph.D. students. The CryptoLUX group forms part of the Laboratory of Algorithmics, Cryptology and Security (LACS), whose official Internet presence can be found at http://lacs.uni.lu. This wiki serves as an informal platform for the presentation of ongoing research projects and the dissemination of research outcome other than peer-reviewed publications (e.g. tools for cryptanalysis, source code of cryptographic software) that would not really fit on the official LACS website. We do our best to ensure the correctness of the information provided by this wiki, but, of course, we can not guarantee that the content is suitable for any particular purpose, especially if it covers work in progress.

Mission and Vision

The mission of the CryptoLUX group is to define, conduct, and disseminate leading-edge research in cryptology (and closely related fields), and to pass the knowledge gained from research on to students and industry partners. CryptoLUX is one of the few academic research teams worldwide that possesses expertise across the full spectrum of cryptology, ranging from theoretical foundations to implementation aspects and applications. Our mission and objectives are devised in accordance with the three main goals of the University of Luxembourg, which are teaching, research and knowledge transfer at the highest international level. Members of CryptoLUX collaborate with top research groups around the world and participate in activities of ECRYPT, the European network of excellence in cryptology. Our current research projects cover a wide variety of topics including algorithm design (block ciphers, hash functions, etc.), cryptanalysis, communication security and anonymity, efficient implementations, side-channel attacks, and reverse engineering.

Emerging information and communication technologies, such as cloud computing or the Internet of things, pose a number of unique challenges related to the design and implementation of cryptographic primitives, which has initiated a large of body of research in these areas. Nonetheless, the number of cryptanalytic attacks (both traditional ones as well as side-channel attacks) is steadily increasing, and many of these attacks have led to devastating security breaches with fatal consequences. We envision CryptoLUX to be in the forefront of an international research community that tackles these challenges and develops innovative solutions for complex security problems based on a solid cryptographic foundation. To achieve this, we strive for a greater understanding of how cryptosystems get broken (or otherwise fail) in the real world, how they can be designed and implemented to better resist attacks, and how they should be used to build secure systems and networks.

We organized ESC 2015

ESC (Early Symmetric Crypto) is a Dagstuhl-like seminar series on symmetric cryptography that fosters collaboration instead of competition. ESC 2015 will take place January 12–16, 2015 in Clervaux, a town in Ardennes. The program chairs of ESC 2015 are Alex Biryukov, Joan Daemen, Stefan Lucks, and Serge Vaudenay. More information can be found here.
