一种AES S盒改进方案及其硬件设计.

This paper presents a novel S-box generation scheme to enhance the security of the Advanced Encryption Standard（AES） algorithm. After analyzing the existing issues with S-boxes, a new S-box is constructed based on the principles of S-box construction and its cryptographic properties. This is achieved by selecting new irreducible polynomials and affine transformations while adjusting the order of affine transformations and multiplicative inversion operations. The newly generated S-box is compared with the S-box of AES and other improved S-boxes in terms of algebraic terms and strict avalanche criteria distance. The results demonstrate that the new S-box exhibits superior algebraic properties and effectively defends against algebraic attacks. Furthermore, the new S-box is subjected to hardware design and optimization. The DC synthesis results reveal that the optimized implementation of the new S-box in the finite field consumes 12% fewer resources compared to traditional finite field implementations and 41% fewer resources compared to lookup table methods. This paper substantiates the superiority of the new S-box in terms of security over the existing S-boxes. It also applies the new S-box to AES software and hardware designs, with the correctness of the implementation verified through simulation testing. [ABSTRACT FROM AUTHOR]
