摘要
基于Feldman可验证秘密共享技术和零知识证明方法,提出了一种计算上安全的数字签名方案,并在此基础上提出了一个容忍入侵的CA方案;通过对CA系统的可用性、机密性和抗假冒服务器攻击等方面的分析,得知方案较为完善.
In this paper, we introduced a digital signature scheme based on the method of secret share and zero-knowledge proofs. Then based on the digital signatrue scheme we introduced a intrusion tolerant CA scheme. Through the analysis of CA system's usability and confidentiality ,we draw the conclusion that the scheme is almost perfect.
