摘　　要：为了进一步提高禽畜种苗交易系统的安全性与可靠性,使用入侵容忍技术,设计由多台服务器组成、基于帕累托分布的禽畜种苗交易系统入侵容忍模型,每台服务器的结构不同但禽畜种苗交易网站服务内容相同,具有响应结果一致性。使用Matlab进行仿真试验,仿真结果表明:与传统的单服务器模式相比较,本模型在受到攻击时,即使其某组件遭破坏或被控制,仍能保障禽畜种苗交易系统服务数据的安全性和完整性,对外提供正常或降级的服务,具有更显著的网络入侵容忍性。To further enhance the safety and reliability of livestock seeds trading system, the intrusion tolerance technology was used and the livestock seed trading system of intrusion tolerance model was designed composed by multiple servers and based on the Pareto distribution. A mathematical model was established using Matlab simulation. The results showed that compared with the traditional application modes, this model could still ensure services data integrity and confidentiality of livestock seeds trading system and ensure the entire system operation of key function under a component by attacked even if destroyed or controlled. Thus it was able to provide normal or downgrading of external services. It has been more targeted and guidance and has more significant intrusion tolerance in the protection of system security.
