基于离散对数的容忍入侵的代理盲签名方案
Intrusion-tolerant proxy blind signature scheme based on discrete logarithm
摘要
Abstract
To defend the forgery attacks of the original signer and signature receiver in the scheme of proxy blind signature,this paper studies the problem of the signature algorithm. Based on the new( t, n) secret sharing mechanism,the private key of the Certificate Authority( CA) is separately stored by using its identity as the mark of private key so that it can provide the intrusion tolerance for the securing Private Keys. Rather than preventing intrusions or attacks to ensure safety of CA,the project ensures that the confidential information of the CA system will not be exposed when a minority of components are attacked. The research results show that even if certain users are spitefully attacked, the system still works properly.关键词
