The software-efficient stream cipher HC-256 was proposed by Wu at FSE 2004. Due to its impressive performance, the cipher was also a well-received entrant to the ECRYPT eSTREAM com...
In this paper we present new and more accurate estimates of the biases of the linear approximation of the FSM of the stream cipher SNOW 2.0. Based on improved bias estimates we als...
Abstract. We present a distinguishing attack against SOBER-128 with linear masking. We found a linear approximation which has a bias of 2−8.8 for the non-linear filter. The atta...
Abstract. This article investigates the relevance of the theoretical framework on profiled side-channel attacks presented by F.-X. Standaert et al. at Eurocrypt 2009. The analyses ...
Rijndael is a block cipher designed by V. Rijmen and J. Daemen and it was chosen in its 128-bit block version as AES by the NIST in October 2000. Three key lengths - 128, 192 or 25...
