In this paper, we describe the design of a new family of block ciphers based on a Lai-Massey scheme, named FOX. The main features of this design, besides a very high security level...
Abstract. In this paper we propose a new family of very efficient hardware oriented block ciphers. The family contains six block ciphers divided into two flavors. All block ciphers...
The block cipher family for lightweight devices, KTANTAN, is analyzed in this paper. We propose a new cryptanalysis method which improves results of Meet-in-the-Middle attacks on K...
Abstract. This paper presents the first results on AIDA/cube, algebraic and sidechannel attacks on variable number of rounds of all members of the KATAN family of block ciphers. Ou...

In this paper we present an improvement of the differential attack on hash functions based on block ciphers. By using the specific properties of the collision attack on hash functi...
