Abstract

Based on the automatic search algorithm to solve differential characteristic and linear characteristic, it has become hot topic in differential and linear attack. This paper presented a differential characteristic and linear characteristic method based on the half-byte MILP model for automatic search cryptanalysis. It analyzed the LED lightweight block cipher and solved the number of active S-boxes with fewer variables and constraint inequalities. It obtained at least 25 active S-boxes in 4 rounds, which was same as theoretical value given by the LED designer, verified the correctness of the half-byte MILP model. Finally, this paper calculated the maximum differential characteristic probability and the maximum linear characteristic probability of LED, which proves that it can resist differential attack and linear attack.
