Edon80 is a recent stream cipher design that has advanced to the third and last phase of the eSTREAM project. It has remained unbroken and untweaked since it was designed and submi...
Klimov and Shamir proposed a new class of simple cryptographic primitives named T-functions. For two concrete proposals based on the squaring operation, a single word T-function an...
Sequence compression is one of the most promising tools for strengthening pseudo-random generators used in stream ciphers. Indeed, adding compression components can thwart algebrai...
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...
ABC v3 is a stream cipher proposed as a candidate to ECRYPT Estream Project which enters the second evaluation phase. Its key length is 128 bits. In this paper, We show that, ther...
