M.Sc., Ph.D. students and postdocs

If you are interested in doing M.Sc. final project (ex. ERASMUS program), Ph.D. or postdoc in analysis/design of symmetric crypto primitives (block/stream ciphers, hash or mac) at the University of Luxembourg, please feel free to send me an e-mail with your CV. For a computer science M.Sc. program in "Cryptography, Security and Trust" at the university of Luxembourg please see this link. Note that you can enter directly to the 2nd year of this program, if you have enough credits.

I'm in the Program Committee of:
9th Intern. Conf. on Inf. Security and Cryptology (ICISC06) 30 Nov.- 01 Dec. 2006
Busan, Korea
acceptance rate: 27/128 = 0.21
VietCrypt'06 25-28 Sep. 2006
Hanoi, Vietnam
acceptance rate: 24/80 = 0.30
WISSEC'06 8-9 Nov. 2006

submission: (TBA)
Asiacrypt'2007 2-6 Dec. 2007
Kuching, Malaysia
submission: 1 June 2007 (tentative)
In the number of submissions I do not count double submissions, since they are immediately rejected thus posing no competition.

Presentation of a new AES-based stream cipher called LEX which is 2-3 times faster than AES. Aarhus, Denmark, 2005. (Slides in PDF, updated 12.01.2007)
I'll be giving talk at Santa-Crypt, Prague, Dec. 2007.
I'll be giving talk at Dagstuhl seminar on symmetric crypto, 7-12 Jan. 2007.

Brief Bio

Alex Biryukov is currently an assistant professor at the University of Luxembourg. Alex has been formerly a visiting assistant professor at K.U.Leuven (ESAT, COSIC group), Belgium, working with Prof. Bart Preneel.  Alex was participating in the development of European standards for Signature, Integrity and Encryption Schemes (NESSIE project)  and in the European Strategic Roadmap for CRYPTO (STORK project).  He is now taking part in the FP6 Network of Excellence ECRYPT which is a consortium of 30 European university and industry teams (Cryptology and Watermarking 2003-2007). He has been teaching a phd-level course on "Methods of Cryptanalysis" during the winter 2002/2003 in Leuven and a similar graduate level course at Weizmann. Alex is actively involved in cryptographic research, often gives talks at the international conferences and workshops, consults in applied cryptography. He has served as a program committee member for more than 15 international conferences and workshops, including the top conferences in the field of cryptography such as EUROCRYPT, CRYPTO, ASIACRYPT (with acceptance rates below 1 out of every 5 submissions). 

Alex was previously a post-doc at the Applied Mathematics and Computer Science department of the Weizmann Institute of Science (Rehovot, Israel), working with Prof. Adi Shamir

Alex has completed in 1994 his M.Sc. on "Cryptanalysis and Improvement of the Data Encryption Standard" at the Technion,(Haifa, Israel) under the supervision of Prof. Eli Biham. He has completed his Ph.D in 1999 on "Methods of Cryptanalysis" at the Technion , (Haifa, Israel) under the supervision of Prof. Shimon Even and Prof. Eyal Kushilevitz. Alex is a member of the International Association for Cryptologic Research (IACR) since 1994.

His expertise includes all aspects of analysis and design of secure cryptographic primitives. Interests include all aspects of information security,  data-mining, computer-intelligence and algorithms in general.

CV is available upon request.


Set is nice game for 6+ year old kids. Children are surpirisingly good at it and provide quite some competition for the adults.

12 cards are placed on the table as shown on the picture. The cards differ by color, shape, number of elements, fill style. There are 3 colors,  3 shapes, 3 fill styles. The idea is to pick 3 cards which have either all properties the same or all different. Such triplet of cards would be called a set. The player who notices a "set" has to call "Set!"  and then show it. If  he is correct he scores +1, and if he has made a mistake  -1. The "set" cards are withdrawn and replaced by the new three cards from the deck.  The player, who has the highest score when the deck is finished  is the winner.

There are 3 sets on the picture.
