摘要
本文对两类ElGamal型签名方案的安全性和基于两类签名方案的通行字认证方案进行了分析和讨论。通过对这些问题的研究,可以对两类ElGamal型签名方案的安全性、性能和相互关系有新的认识。
The security relationship between p-schemes and MR(p)-schemes is analysed and their security classes are given. In addition, some multisignature schemes based on MR(p)-schemes and some password authentication schemes based on unproved ElGamal signature schemes are proposed. The results may be helpful for new understanding of the security, performance and relationship of two kinds of ElGamal type signature schemes.
