Abstract

In this paper, we give a theoretical analysis of χ2 attack proposed by Knudsen and Meier on the RC6 block cipher. To this end, we propose a method of security evaluation against χ2 attack precisely including key dependency by introducing a method "Transition Matrix Computing." Previously, no theoretical security evaluation against χ2 attack was known, it has been done by computer experiments. We should note that it is the first result concerning the way of security evaluation against χ2 attack is shown theoretically.
