基于伪随机排列的密码模型及其在MATLAB中的实现

Cryptogram Modle Based on Pseudorandom Permutation and Achieving in MATLAB

给出了关于密码编码学的一般数学模型,在此基础上提出了一种新颖的能用于中文文稿加密的实用有效的编码方法:基于伪随机排列的密码模型(PRP算法),并在MATLAB中实现了上述模型。通过唯密文攻击和已知明文攻击的密码分析,得知该算法具有很强的抵抗攻击能力。

Gave a general mathematical model of cryptography, then put forward a novel and available cryptogram method for Chinese text： the Encrypt Model Based on Pseudorandom Permutation （the PRP algorithm ）, and achieved it in MATLAB. By the cryptogram analysis of Ciphertext only and Known plaintext, its strong ability to holdout attack has been verified.
