Design and Analysis of Multivariate Hash Function
Author(s): 
Pages: 237-241
Year: Issue:  1
Journal: Acta Electronica Sinica

Keyword:  密码学Hash函数MQ问题多变元多项式;
Abstract: 本文在基于非线性多变元多项式方程组难解性的基础上,提出了一种新的Hash算法,新算法与目前广泛使用的Hash算法相比具有下列优点:安全性基于一个公认的数学难题;输出Hash值长度可变;引入了整体随机性,从一族Hash函数中随机选择Hash函数而不是随机化消息本身;设计自动化,用户可根据实际需求构造满足其特定要求的Hash函数.本文还详细讨论了新Hash算法的安全性、效率和性能,并通过仿真实验,指出...
