A vast amount of literature on stream ciphers is directed to the cryptanalysis of LFSR-based filters and combiners, resulting in various attack models such as distinguishing attac...

We present a realization of an LFSM that utilizes an LFSR. This is based on a well-known fact from linear algebra. This structure is used to show that a previous attempt at using a...

We present several attacks against Achterbahn, one of the new stream ciphers proposed to the eSTREAM competition. Our best attack breaks the reduced version of the cipher with comp...

Abstract. A new stream cipher, Grain, is proposed. The design targets hardware environments where gate count, power consumption and memory is very limited. It is based on two shift...
