We describe an enhanced version of the TWINKLE factoring device and analyse to what extent it can be expected to speed up the sieving step of the Quadratic Sieve and Number Field S...
Abstract. This paper addresses the problem of obtaining new construction methods for cryptographically significant Boolean functions. We show that for each positive integer m, ther...
Abstract. We discuss the special requirements imposed on the underlying cipher of systems which encrypt each sector of a disk partition independently, and demonstrate a certificati...
In this paper, we present techniques to protect bitslice block ciphers against power analysis attacks. We analyze and extend a technique proposed in [14]. We apply the technique to...
We improve the best attack on Rijndael reduced to 6 rounds from complexity 272 to 244 . We also present the first known attacks on 7- and 8-round Rijndael. The attacks on 8-round R...
