In this paper we study structural properties of SPN ciphers in which both the S-boxes and the affine layers are involutions. We apply our observations to the recently designed Rijn...
Abstract. Bellare and Kohno introduced a formal framework for the study of related-key attacks against blockciphers. They established sufficient conditions (output-unpredictabilit...

Recently a powerful cryptanalytic tool—the slide attack— was introduced [3]. Slide attacks are very successful in breaking iterative ciphers with a high degree of self-similari...
Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...
