The Multiplicative Persistence Conjecture Is True for Odd Targets

Autor: Brier, Eric, Clavier, Christophe, Gutsche, Linda, Naccache, David

In 1973, Neil Sloane published a very short paper introducing an intriguing problem: Pick a decimal integer $n$ and multiply all its digits by each other. Repeat the process until a single digit $\Delta(n)$ is obtained. $\Delta(n)$ is called the \tex

SM3, the Chinese standard hash algorithm inspired from SHA2, can be attacker by similar means than SHA2 up to an adaptation to its differences. But this kind of attack is based on targeting point of interest of different kinds, some are end of comput

Study of a Parity Check Based Fault-Detection Countermeasure for the AES Key Schedule

Autor: Clavier, Christophe, Francq, Julien, Wurcker, Antoine

Publikováno v: [Research Report] 2015/877, IACR Cryptology ePrint Archive. 2015

In this paper we study a parity check based countermeasure proposed by Chen et al. that thwarts their attack by detecting byte fault injection during the AES key schedule process. We provide a generalization of their approach that allows to derive pa
