【Abstract】 The design of standards in the P permutation of the DES algorithm is discussed. By reconstructing a P permutation we solve the problem that Hamiltonian Cycles can construct the AB graph, thus correct the wrong view that the AB graph cannot construct by Hamiltonian Cycles. Meanwhile, this enhances the infusibility of P permutation.更多还原
