SOSEMANUK is a word-oriented stream cipher submitted to the ECRYPT stream cipher project, with a variable-length key between 128 and 256 bits. The algorithm is similar to the strea...
We present and analyze attacks on additive stream ciphers that rely on linear equations that hold with non-trivial probability in plaintexts that are encrypted using distinct keys....
The stream ciphers Py, Pypy and Py6 were designed by Biham and Seberry for the ECRYPT-eSTREAM project in 2005. The ciphers were promoted to the ‘Focus’ ciphers of the Phase II ...
