The provable security for 13 round Skipjack-like structure was presented. The maximum differential probability was proved as bounded by a small value to show that the block cipher was secure against differential Cryptanalysis (DC). Results showed that the maximum differential probability of a 13 round Skipjack-like structure was bounded by p4, where p was the maximum differential probability of round function.
