CryptoLUX is a cryptology research group within the Computer Science and Communications ([http://csc.uni.lu CSC]) research unit of the [http://www.uni.lu 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.

Emerging information and communication technologies, such as [http://en.wikipedia.org/wiki/Cloud_computing cloud computing] or the [http://en.wikipedia.org/wiki/Internet_of_Things 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 <b>in the forefront of an international research community</b> that tackles these challenges and develops <b>innovative solutions for complex security problems based on a solid cryptographic foundation</b>. 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.

CryptoLUX is a cryptology research group within Security and Trust interdisciplinary center (SnT) and 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 a permanent staff member (Johann Großschädl), several postdoctoral researchers, and about half a dozen Ph.D. students. The CryptoLUX group also forms part of the Laboratory of Algorithmics, Cryptology and Security (LACS). This wiki serves as an informal platform for the presentation of ongoing research projects and the dissemination of research outcome, ex. peer-reviewed publications, tools for cryptanalysis, source code of cryptographic software. 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. Our current research projects cover a wide variety of topics including algorithm design (block ciphers, hash functions, proofs of work), cryptanalysis, communication security and privacy enchancing technologies, financial technologies/blockchain, 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 2017

ESC (Early Symmetric Crypto) is a Dagstuhl-like seminar series on symmetric cryptography that fosters collaboration instead of competition. ESC 2017 took place January 16–20, 2017 in Canach, Luxembourg. The program chairs of ESC 2017 were Alex Biryukov, Joan Daemen, Stefan Lucks, and Serge Vaudenay. More information can be found here.

Open Positions, Jobs

We are currently looking for three post-doctoral researchers (research associates) and a Ph.D. student to join the CryptoLux group in Fall 2020. Further information about these positions can be found on the vacancies page.
