- 根据JPEG2000格式的特性，改变在其算术编码时采用的概率状态迁移表可达到加密图像的效果-According to the characteristics of JPEG2000 format change in its arithmetic coding used in the probability of state migration table can achieve the effect of encrypted image
Introduction_to_Cryptanalyst
- 加密算法是计算机科学中的一个分支。本书是一本简单介绍加密算法的英文书籍，并包含了对常见英文词根出现概率的分析-Computer encryption algorithm is a branch of science. This book is a simple encryption algorithm, introduced in English books, and contains a common root in English appear probability analysis
IDEA
- Markov密码的(差分链)转移概率矩阵是双随机矩阵，其第二大（模）特征值对于确定Markov密码必要的迭代轮数有重要价值。该程序由本人编写，实现了求IDEA密码的缩小模型IDEA(8)的转移概率矩阵П0第二大（模）特征值-Markov password (differential chain) transition probability matrix is a doubly stochastic matrix, its second largest (modulus) eigenvalue
