摘要：

We present Gray S-box for Advanced Encryption Standard. Gray S-box is constructed by adding binary Gray code tran. formation as a preprocessing step to original AES S-box. Gray S-box corresponds to a polynomial with all 255 non-zero terms in comparison with 9-term polynomial of original AES S-box. This increases the security for S-box against algebraic attacks and interpolation attacks. Besides, as Gray S-box reuses AES S-box as a whole, Gray S-box inherits all advantages and efficiency of any existing optimized implementation of AES S-box. Gray S-box also achieves important cryptographic properties of AES S-box, including strict avalanche criterion, nonlinearity, and differential uniformity.
