The 4th BIU Winter School

 

SYMMETRIC ENCRYPTION IN THEORY AND IN PRACTICE

JANUARY 27-30, 2014

 

SCHOOL OVERVIEW

The winter school will study symmetric encryption in theory and in practice. The school will include a study of the theoretical foundations of symmetric encryption on the one hand, and practical constructions and cryptanalysis on the other hand. These two topics will provide a broad basis for all participants. The school will then proceed to study advanced constructions like tweakable block ciphers, format preserving encryption, disk encryption and advanced types of authenticated encryption. Finally, the school will conclude with advanced and recent attacks on symmetric encryption in SSL/TLS, IPsec, SSH and more. The school program includes approximately 24 hours of lectures and a social dinner.

The target audience for the school is graduate students and postdocs in cryptography (we will assume that participants have taken at least one university-level course in cryptography). However, faculty, undergrads and professionals with the necessary background are all welcome. The winter school is open to participants from all over the world; all talks will be in English.
