基于Python语言的3DES算法优化

Optimization of 3DES Cryptography Algorithm Based on Python

介绍了3DES加密算法的原理,描述了对Python语言自带模块pyDES模块中3DES算法的优化过程,分析了3DES算法编程实现过程中效率优化时所遇到的问题及解决方法;最后使用Python语言中的profile工具对优化后的算法进行了测试,数据表明优化后的3DES算法提高了原算法的加解密速度和安全性。

This paper discusses the theory of 3DES Cryptography algorithm, describes the optimization process of PyDES module, which is a pure python module that implements the DES and Triple-DES algorithms; and analyzes the problems and solutions encountered in the optimization process; Finally, the optimized algorithm was tested by profile which is a tool for python program testing, and the result shows that the optimized algorithm can Enhance the Security and speed of the original algorithm.
