| 摘 要： | 提出了一个入侵容忍CA（Certificate Authority，认证中心）系统，在此系统中构造了一个基于椭圆曲线密码体制的（t，n）门限签密方案，该方案是数字签名和公钥加密的有机集成，不仅减少了系统的开销，并使得系统能探测故障服务器和克服签密合成者的欺骗。最后给出了该方案的安全性分析和进行单个证书请求的性能测试结果。

| Abstract: | In this paper an intrusion tolerant CA system was presented.A new scheme of(t,n) threshold signature encryption based on ellipse curve cryptosystem was presented in this system.The scheme perfectly integrates digital signature scheme with public key cryptosystem that not only reduced the overhead of system but also enabled the system to detect corrupted share servers and cheaters.Finally the security and the performance testing result of single certification requirement of this system were proposed. |
