摘　　要：在安全系统设计中,通常使用代理服务器作为系统门户,以保护系统并屏蔽系统的内部结构。提出一种基于主代理的代理服务器群方案和相应的主代理选举算法。发现主代理被入侵时,该方案通过协商机制替换有问题的主代理,并利用选举算法重新选举出新的主代理,提高了代理服务器的可用性和安全性。While designing a security system, a proxy server is usually used as gateway system to protect the system and screen its inner structure. This paper proposes a proxy server group scheme based on leader proxy and the relevant election algorithms for electing leader proxy. When finding the leader proxy is compromised, this scheme replaces it by consultation mechanism and elects another leader proxy by using election algorithms. The availability and security of proxy servers are enhanced.
