摘　　要：针对目前P2P路由机制受到许多网络威胁,现有的安全路由算法无法满足P2P网络安全需求的问题。提出了一种基于安全路由算法的P2P网络安全性能优化策略,引入了Chord安全路由算法,并且对其进行改进,提出了设置安全邻近距离和双向查找机制的策略,还使用迭代的方法对双向查找机制进行安全性能的优化。实验表明,基于安全路由算法的P2P网络安全性能优化策略大大提高了P2P网络的安全性能,本方案切实有效。By many network threats against P2P routing mechanism, existing security routing algorithm can not meet the needs of the P2P network security issues. Proposed a secure routing algorithm based P2P network security performance optimization strategies, and the introduction of the Chord security routing algorithm, and to improve it, and put forward the strategy of the set security neighboring distance and two-way lookup mechanism, using an iterative method of two-way Find mechanisms for safety performance optimization. The experiments show that the secure routing algorithm based P2P network security performance optimization strategy to greatly improve the safety performance of P2P networks, this program is effective.
