Abstract. While it is known previously that the cycle lengths of individual components of the AES round function are very small, we demonstrate here that the cycle length of the S-...
Rijndael is the new Advanced Encryption Standard designed by V. Rijmen and J. Daemen and chosen as AES by the NIST in October 2000. Surprisingly, the number of cryptanalyses agains...
Abstract. When cryptosystems are being used in real life, hardware and software implementations themselves present a fruitful field for attacks. Side channel attacks exploit infor...
Abstract. In this article we present a low-cost coprocessor for smartcards which supports all necessary mathematical operations for a fast calculation of the Elliptic Curve Digital...
We present an implementation of elliptic curves and of hyperelliptic curves of genus 2 and 3 over prime fields. To achieve a fair comparison between the different types of groups,...
