This paper presents several methods to construct trapdoor block ciphers. A trapdoor cipher contains some hidden structure; knowledge of this structure allows an attacker to obtain ...
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 [10], Buchmann, Pyshkin and Weinmann have described two families of Feistel and SPN block ciphers called Flurry and Curry respectively. These two families of ciphers are fully p...
We propose a general framework for differential and linear cryptanalysis of block ciphers when the block is not a bitstring. We prove piling-up lemmas for the generalized different...
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...
