一种快速的键控散列算法

A Fast Keyed Hash Algorithm

介绍了MD5算法及对它的安全性能分析 ,提出了一个基于MD5的键控散列算法。新算法具有一个可变长度密钥 ,输出 2 5 6位的报文鉴别码 (MAC)。分析了新算法的安全性和运行效率 ,结果表明 ,该算法安全 ,运行效率高。

This paper introduces the MD5 algorithm and security analysis.A new keyed hash algorithm based on MD5 is proposed.The new algorithm can use a variable length key,and its output is 256-bit message authentication code(MAC).Security and performance of the new algorithm are analyzed in the paper.The result shows that keyed hash algorithm is secure and fast.
