Maximum average of differential probability is one of the security measures used to evaluate block ciphers such as the MISTY cipher. Here average means the average for all keys. Thus, there are keys which yield larger maximum differential probability even if the maximum average of differential probability is sufficiently small. This paper presents the cases in which the maximum differential probability is larger than the maximum average of differential probability for some keys, and we try to determine the maximum differential probability considering the key effect.
