The AES block cipher has a 128-bit block length and a user key of 128, 192 or 256 bits, released by NIST for data encryption in the USA; it became an ISO international standard in ...
Abstract. In this paper, we fully break the Algebraic Surface Cryptosystem (ASC for short) proposed at PKC’2009 [3]. This system is based on an unusual problem in multivariate cr...
Secret handshakes were recently introduced [BDS+ 03] to allow members of the same group to authenticate each other secretly, in the sense that someone who is not a group member ca...

The paper analyzes cache based timing attacks on optimized codes for Advanced Encryption Standard (AES). The work justifies that timing based cache attacks create hits in the fi...
We provide a functional encryption system that supports functionality for regular languages. In our system a secret key is associated with a Deterministic Finite Automata (DFA) M....
