摘要
Rijndael作为美国高级加密标准算法,将在未来30年里代替DES在各领域得到广泛应用。与其安全性已经并正在得到广泛而全面的讨论分析相比,其优化实现方面的研究则比较少见,文章给出了Rijndael主要部件S盒、列变换及其逆运算以及整个圈变换的优化及其原理,从运算单位、数据访问时间和简化矩阵运算等方面提高算法的实现效率。
As the Advanced Encryption Standard of United States,Rijndael will be used to replace DES for the following 30 years.It will of course have a wide use in various aspects.Its security has been discussed in depth while the optimization in its implementation are studied much less.It gives the optimization and the corresponding principle of the key components such as S box,MixColumn and its inverse,as well as that of the whole round transformation.
