The SOSEMANUK stream cipher is one of the finalists of the eSTREAM project. In this paper, we improve the linear cryptanalysis of SOSEMANUK presented in Asiacrypt 2008. We apply th...
Abstract. Grain [11] is a lightweight stream cipher submitted by M. Hell, T. Johansson, and W. Meier to the eSTREAM call for stream cipher proposals of the European project ECRYPT ...
Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linea...
The previous key recovery attacks against Helix obtain the key with about 288 operations using chosen nonces (reusing nonce) and about 1000 adaptively chosen plaintext words (or 23...
