摘　　要：在密码协议的实际运行中,为保护密码协议安全运行,针对密码协议上攻击产生的原因,文中设计了两种能容忍入侵的密码协议自适应调整策略:算法自适应调整策略和参数自适应调整策略,能根据攻击的类型,动态调节密码协议的运行,以容忍/阻止一部分攻击行为,更好的保护密码协议的运行安全,并对两种策略的原理进行了详细的介绍,对它们的性能进行了仿真实验与分析,验证了这些策略的有效性。By analyzing the causes of attacking on cryptographic protocol, two adaptive re-configuration policies, that is, algorithmic and parametric, for holding back the attacks on cryptographic operation are designed for protecting operation security of cryptographic protocol in practice. These policies of intrusion tolerance, by adjusting the use of cryptographic protocol, and tolerating or preventing part of attacks, protect the safety of cryptographic protocol performance. The principle of those two policies is discussed in detail, the performance analyzed through the simulation experiment, and the validity of policies verified.
