We present our further observations on the structure of the AES algorithm relating to the cyclic properties of the functions used in this cipher. We note that the maximal period of...

Until now in cryptography the term collision was mainly associated with the surjective mapping of different inputs to an equal output of a hash function. Previous collision attack...

Hypothesis tests have been used in the past as a tool in a cryptanalytic context. In this paper, we propose to use this paradigm and define a precise and sound statistical framewo...

In this paper, we revisit the security of several message authentication code (MAC) algorithms based on block ciphers, when instantiated with 64-bit block ciphers such as DES. We e...

Abstract. In this paper, we present differential attacks on the selfsynchronizing stream cipher KNOT. Our best attack recovers 96 bits of the secret key with time complexity of 26...

We use the notion of covering sequence, introduced by C. Carlet and Y. Tarannikov, to give a simple characterization of bent functions. We extend it into a characterization of plat...

In this paper, we investigate the security, in the Luby-Rackoff security paradigm, of blockcipher modes of operation allowing to expand a one-block input into a longer t-block ou...
