### Paper: Theoretical Analysis of Correlations in RC6''

Authors: Masahiko Takenaka Takeshi Shimoyama Takeshi Koshiba URL: http://eprint.iacr.org/2002/176 Search ePrint Search Google In this paper, we give the theoretical analysis of Chi-square attack proposed by Knudsen and Meier on the RC6 block cipher. To this end, we propose the novel method of security evaluation against Chi-square attack precisely including key dependency by introducing a technique Transition Matrix Computing.'' On the other hand, the way of security evaluation against Chi-square attack has not been known except the computer experiment. We should note that it is the first results the way of security evaluation against Chi-square attack is shown theoretically. Using this method, we can obtain the weakest keys'' against the attack.
