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. Khazad is a new block cipher initially proposed as a candidate to the NESSIE project. Its design is very similar to Rijndael, although it is a 64-bit block cipher. In thi...
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 ...
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 ...
