摘要: 数字签名系统中需用一个安全可靠且易实现的Hash函数.Hash函数有严格的要求, 其构造及性能分析难度都较大.本文构造了一个比较实用的Hash函数, 并对其性能作了较全面的分析.同时指出了Hash函数在票据防伪、防止非法修改应用软件中的应用.
关键词: 数字签名Hash函数单向函数弥散性S盒中心距离    
Abstract: A Hash function of safety、reliability and simple realization is often used in digital signature system. A Hash function has some strict demands, and its structure and properties' analyses are very difficult. In this paper, a useful Hash function is structured, and its properties are analysed more perfectly. In addition, the paper points out its applications in discerning the false bills from the genuine and preventing from illegally modifying practical software.
Key words: digital signature    Hash function    one direction function    diffusion property    S box    centural distance
