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...
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. 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-...
This paper is motivated by the design of AES. We consider a broader question of cryptanalysis of block ciphers having very good non-linearity and diffusion. Can we expect anyway, ...
This paper is about the design of multivariate public key schemes, as well as block and stream ciphers, in relation to recent attacks that exploit various types of multivariate alg...
Abstract. Since being officially selected as the new Advanced Encryption Standard (AES), Rijndael has continued to receive great attention and has had its security continuously eva...
In this note we study security of 128-bit key 10-round AES against the boomerang attack. We show attacks on AES reduced to 5 and 6 rounds, much faster than the exhaustive key searc...
