講演題目:「FO Relation of MISTY1 and key-dependent attack」
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.
