The Algebra Properties of the S-Boxes of Several Block Ciphers

摘要：

S-boxes bring nonlinearity to block ciphers and strengthen their cryptographic security.A detailed analysis of the cryptographic properties of the SMS4,AES,Camellia and SEED S-boxes are made in this paper.Some algebraic properties of boolean function of S-boxes such as balanceness,nonlinearity,algebraic degree and walsh spectrums are well investigated.We reveal the advantages and disadvantages of those Sboxes used in SMS4,AES,Camellia and SEED as compared with each other.
