摘要: 分析了一种基于混沌构造的Hash函数方法,发现其中存在着碰撞。提出了一种基于改进Hash函数的一次数字签名方案,并对此方案的统计性和安全性进行了分析。
关键词: Hash函数, 混沌, 一次签名
Abstract: A Hash function based on chaos has been analyzed and some collisions are found.A new one-time digital signature scheme based on the improved chaos hash function is issued.The statistical properties and simple safety of the scheme are analyzed.
Key words: hash function, chaos, one-time digital signature
