摘要
详细分析了 AES最终入选算法— Rijndael算法的处理过程及其数学原理 ,对密文的频数进行了水平为α=0 .0 0 5的χ2 -检验 ,得出 Rijndael算法密文比特服从概率为 0 .5的二项式分布 ,可见 Rijndael算法的频数具有良好的随机特性。
This paper gives a detailed analysis of the processing procedure and the mathematical rationale of Rijndael arithmetic, the final AES selected arithmetic. After the χ 2-check of the cipher frequency on the levelof α=0.005, the paper asserts that the cipher bit-stream follows the binomial distribution B(n, 0.05). So the bits of the Rijndael cipher have a pretty random property.
