Abstract. Synchronous stream ciphers need perfect synchronization between sender and receiver. In practice, this is ensured by a resync mechanism. Daemen et al. [10] first describ...

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...

Algebraic attacks on stream ciphers [14] recover the key by solving an overdefined system of multivariate equations. Such attacks can break several interesting cases of LFSR-based ...

This paper presents an operational reconstruction technique of most stream ciphers. We primarily expose it for key-stream generators which consist of several linear feedback shift ...
