We show an optimization technique of algebraic method for higher order differential attack. Our technique is based on linear dependency and makes a small coefficient matrix for algebraic method using redefined unknown variables. We also show a technique of algebraic method for an attack equation which holds probabilistically. We demonstrate our method by attacking five-round MISTY1. Our method needs 221.6 chosen plaintexts and 232.4 computational cost. The computer simulation took about 6 minutes. |
