基于混合离散对数的安全认证研究

Study about Secure Authentication Based on Composite Discrete Logarithm

文章在研究混合系数的离散对数问题(也即信息不可识别性)的基础上,提供一种新的认证,这种认证比因式分解有更好的安全性,而且从证明者角度看来有更高的效率。最后,基于信息不可识别性,得到一个安全性与因式分解相同的盲签名。

The problem of Composite Discrete Logarithm have been studied in this paper.A new secure have been giv-en.Finally a new blind signature scheme be put forward which security base on decompose factor.High efficiency is the most peculiarity of the blind signature algorithm.
