Abstract

Impossible-differential attacks are a very efficient form of cryptanalysis against block ciphers. In this paper, we improve the existing impossible-differential attacks against Rijndael-160 and Rijndael-224.

Note that in many attacks and in the one presented here, the bit-conditions are not independent but considering a pairwise independence leads to overestimate the attack complexity.
