Cache Timing Analysis of LFSR-Based Stream Ciphers
Cache timing attacks are a class of side-channel attacks that is applicable against certain software implementations. They have generated significant interest when demonstrated ag...

Online Ciphers and the Hash-CBC Construction
We initiate a study of on-line ciphers. These are ciphers that can take input plaintexts of large and varying lengths and will output the ith block of the ciphertext after having p...

Cryptanalysis of SOBER-t32
Abstract. Sober-t32 is a candidate stream cipher in the NESSIE competition. Some new attacks are presented in this paper. A Guess and Determine attack is mounted against Sober-t32 ...

Security Weaknesses in a Randomized Stream Cipher
Abstract. TriStrata appears to have implemented a variation of Maurer’s randomised cipher. We define a variation of Maurer’s cipher that appears to be similar to the TriStrata...

Rewriting Variables: The Complexity of Fast Algebraic Attacks on Stream Ciphers
Recently proposed algebraic attacks [2, 6] and fast algebraic attacks [1, 5] have provided the best analyses against some deployed LFSR-based ciphers. The process complexity is exp...
