Abstract(in English) | RC6 is a block cipher proposed by Rivest in 1998, which consistsof the arithmetic operations and bit-shifts. So, it is suitable for the software implementation. χ^2-attacks are known to be effective for RC6, and many researches on χ^2-attacks have been proposed. Asymmetcic χ^2 test attack proposed in SCIS2006 recover the key of RC6 efficiently. However, the theoretical success probability is very higher than the experimental success probability, because the theoretical values are estimated on the assumption that the all distributions of χ^2-value of wrong-keys are same. We reconsider the assumption of distributions of χ^2 valus of wrong-keys, and estimate the success probability more strictly. |
