Key-controlled Rijndael algorithm with multiple S-boxes
摘要
根据AESS盒的设计思想构造出了一批密码性能良好的S盒
并从方差的角度对它们的雪崩概率进行了分析。在此基础上
对Rijndael算法中的字节代换步骤SubBytes进行改进
从而提出了一种基于密钥控制的多S盒的Rijndael算法。实验结果表明
改进后的算法对差分攻击的抵抗能力有所提高
雪崩效应更趋合理。
Abstract
According to the design criterion of S-box in Rijndael algorithm
a number of S-boxes with good crypto-graphic properties were constructed
and the avalanche probabilities of these S-boxes were analyzed from variance point of view.Based on these studies
a key-controlled Rijndael algorithm with multiple S-boxes was proposed with the im-provement of SubBytes algorithm in Rijndael.Experimental results show that the improved algorithm has stronger ability to resist differential attack
and the avalanche effect of the algorithm is more reasonable.
