| 摘 要： | 通过深入分析AES算法,提出一种一次性生成密钥扩展的高效AES算法实现方案。利用一个事先定义的T表存储列混合和字节替换,使MixColumns变成简单的查表而不是域乘。在S3C2440处理器上实现的实验结果表明,该方案提高了算法的运行速度,并可抵抗线形密码分析的攻击。

| Abstract: | By thoroughly investigating AES algorithm,an efficient AES algorithm implementation scheme is proposed for generating KeyExpansion at once.The solution uses a pre-defined T-table to store column mixture and byte replacement to turn MixColumns into a simple look-up table instead of a domain multiplication.Experimental results performed with S3C2440 processors indicate that the scheme improves the operation speed of the algorithm and resists linear cryptanalysis attacks. |
