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...
Abstract. We present a new stream cipher, Rabbit, based on iterating a set of coupled nonlinear functions. Rabbit is characterized by a high performance in software with a measured...

Abstract. Sober-t32 is a candidate stream cipher in the NESSIE competition. Some new attacks are presented in this paper. A Guess and Determine attack is mounted against Sober-t32 ...
In this note we study security of 128-bit key 10-round AES against the boomerang attack. We show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key searc...
In this paper we present a distinguisher targeting towards irregularly clocked filter generators. The attack is applied on the irregularly clocked stream cipher called LILI-II. LI...
In this paper, we analyze the initialization algorithm of Grain, one of the eSTREAM candidates which made it to the third phase of the project. We point out the existence of a slid...
