In this paper we give a specification of a new block cipher that can be called the Courtois Toy Cipher (CTC). It is quite simple, and yet very much like any other known block ciph...
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...
Abstract. The Common Scrambling Algorithm (CSA) is used to encrypt streams of video data in the Digital Video Broadcasting (DVB) system. The algorithm uses a combination of a strea...
Abstract. The main contribution of this paper is a new iterated secretkey block cipher called 3D, inspired by the AES cipher. The 3D cipher has an SPN design, operates on 512-bit b...
Although many strong cryptanalytic tools exploit weaknesses in the data-randomizinig part of a block cipher, relatively few general tools for cryptanalyzing on the other part, the ...
