| 摘 要： | 文章首先说明了Rijndael算法中S盒的四种测试方法,包括差分、线性、雪崩和布尔表达式测试。使用有限域中30个最高次幂为8的不可约多项式利用MATLAB构造不同S盒,然后对这些S盒进行优化测试,发现它们在差分和线性测试上性能相似,在雪崩和布尔表达式测试方面的差别主要在稳定性和分布均匀性上,从这两方面得到了最优的S盒。

| Abstract: | The S-boxes testing methods are described in this paper, including differential testings, linear or correlation testing, avalanche testing, and boolean expressions testing. Then different S-boxes by MATLAB using 30 irreducible polynomials in a finite field are constructed, of which the maximum power is eight. Through their Optimum tests, it is found that they have the similar performances in differential testing and linear or correlation testing. However, the differ-ences in avalanche testing and boolean ex... |
