摘　　要：指出了主密钥安全保护的重要地位.由于传统的方法对此无能为力,提出了一种入侵容忍技术和基于椭圆曲线密码体制的组零知识证明方法有机结合的主密钥合成算法,通过影子服务器的影子安全地保护了主密钥、无信息泄露地验证了主密钥,而且在受攻击后仍能继续工作.利用数学方法严格地证明了它的正确性,通过安全性分析得此策略有效地解决了主密钥的安全保护问题.This paper points out the importance of protecting the main key. Because the conventional methods can do nothing about the flaws at all, this thesis puts forward the arithmetic of synthesized main key, which is based on the organic combination between the intrusion tolerance technology and the group zero-knowledge proof of the Elliptic Curve Cryptography（ECC）. Through the share servers, the main key can be protected safely and validated without leaked information. Furthermore the system can work sequentially after being attacked. And this thesis strictly proves its correctness of the arithmetic by the means of the mathematics, and also reveals that this tactic effectively solves the problem of safely protecting the main key.
