摘要: |
分离了AES密码中S盒的仿射变换,得到了与原密码S盒不同的三种等价密码。研究发现列混合矩阵在很大程度上影响仿射变换的提取,在这种意义上提出了对列混合变换的改进建议。 |
关键词: AES S盒 仿射变换 等价密码 |

Abstract: |
Three kinds of equivalent ciphers of AES are presented by separating S-box's affine transformation. Results from research showed that MixColumn matrix influenced the separation of S-box's affine transformation to a great extent. As a result, suggestions to the improvement of MixColumn algorithms were made. |
Keywords: AES S-box affine transformation equivalent cipher |
