Description
Number systems are behind a lot of implementations. The role of representation is often underrated while its importance in implementation is crucial. We survey here some classes of fundamental systems that could be used in crypotgraphy. We present three main categories:<br/> - systems based on the Chinese Remainder Theorem which enter more generally in the context of polynomial interpolation,<br/> - exotic positional number representations using original approaches,<br/> - systems adapted to operations like the exponentiation.<br/> We stay at the level of the representation system, we do not deal with all the decomposition forms that can be used for accelerating the computation.<br/> lien: http://desktop.visio.renater.fr/scopia?ID=728862***9707&autojoin

Cryptanalysis of full BEANIE
Orateur : Xavier Bonnetain - Inria
BEANIE is a tweakable block cipher recently published at ToSC aiming for memory encryption of microcontroller units. In line with this goal, it handles small plaintexts of only 32 bits and has a low latency. In this paper, we propose the first third-party analysis of the two variants of BEANIE. By carefully leveraging structural properties of the cipher and taking advantage of its distinctive[…]-
