| 摘 要： | 原有对称加密算法采用置换与替换技术.该文提出一种基于圆性质的对称密钥加密算法,采用随机数技术与密码学杂凑函数,使加密后的密文随机分布于n维几何空间,实现了抗密码分析攻击,而穷举攻击在计算上是不可行的.该算法适用于带时间戳加密、短明文加密等应用环境,实验结果验证了其可行性.

| Abstract: | The former symmetric encryption algorithms use substitution and transposition techniques.This paper presents a symmetric encryption algorithm based on circle property.The techniques of random number and cryptographic hash function are used in this algorithm.So the cipher text randomly distributes in the n-dimensional space and led to cryptanalysis being difficult.From the security analysis the brute-force attacks are infeasible.It is applicable for encryptions with timestamp and short plain text encryptions... |
