Welcome to the CryptoLUX Wiki!
CryptoLUX is a cryptology research group within Security and Trust interdisciplinary center (SnT) and the Departement of Computer Science (CSC) 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 and PhD researchers. 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 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.
ESC Seminar series 2008-2017
ESC (Early Symmetric Crypto) was a set of five Dagstuhl-like seminars on symmetric cryptography that fostered collaboration among young and seasoned cryptographers. ESC took place bi-annually in January in various towns in Luxembourg, alternating with corresponding Dagstuhl seminars on Symmetric cryptography. There were around 50 attendees at each session. The program chairs of ESC were Alex Biryukov, Joan Daemen, Stefan Lucks, and Serge Vaudenay. More information can be found here: ESC seminars.
Open Positions, Jobs
We are currently looking for two post-doctoral researchers (research associates) to join the CryptoLux group in early 2025. Further information about these positions can be found on the vacancies page.
