一种新型HASH函数的设计

A New Design of Hash Function

一、Hash函数的设计 Hash函数经常使用在密码技术中,用以进行数据签名和身份验证它通常有三种实现方式:(1)使用数学上的单向函数。例如:基于因子分解或离散对数问题的H妞h函数,往往具有很好的密码学性质,

some design techniques of SHA are showed in this paper,which is a famous Hash Function and has some good features. Two problems are discussed about it,then a new design of hash function based on them is proposed.
