      Title: FO Relation of MISTY1 and key-dependent attack


      Abstract: We present several integral attacks on MISTY1 using the FO Relation, derived from a property used in previous attacks. We also give a formalization of key-dependent attack, in which the key-dependent intermediate value is used. The attack determines whether a key is right by conducting statistical hypothesis test on the intermediate value.
