摘要
对韩国分组密码标准SEED算法两个S盒S1、S2的密码学性质进行了深入的分析,研究了其差分性质、线性结构、平衡性、非线性等性质,通过与美国的高级加密标准AES、欧洲的分组加密标准Camellia的S盒作比较,揭示SEED算法S盒所拥有的一些较好的安全特性。
The eryptographie properties of two S-boxes-S1 and S2 of SEED were analyzed. Some algebraic properties of S-boxes such as differential characteristics, linear structures, balanceness, and nonlinearity were well investigated. Compared with the S-boxes of AES used in USA and Camellia used in European, it was claimed that S-boxes of SEED possessed some better properties of safety.
