摘　　要：研究了安全移动路由算法设计的问题。针对目前代理在网络中进行漫游时,数据安全存在极大威胁,而现有的一些使用移动代理的路由算法或是没有考虑到代理的安全,或安全保护负担过重。为此,提出了一种基于安全移动代理的路由算法的设计思想,使用概率值来构造路由表,通过移动代理在网络节点间的迁移来发现网络状态,更新节点路由表。同时在网络节点处建立信任表,定期生成测试代理在虚拟空间中运行,并对其属性和关键数据进行检测以保证网络节点的可靠性,实现代理在网络中的安全。提出的算法还借助rasshopper移动代理开发平台构造了一个简单网络模型,对其进行了仿真验证。算法提高了路由算法的效率,节约了网络的系统开销,有良好的运用前景。Researching on the secure mobile routing algorithm design problems.For the openness of the network, data safety is badly threatened.Some existing routing algorithms which involve mobile agents do not take agents＇ security into account while the others have heavy burdens on the protection of agents＇ security.This paper proposes an adaptive routing algorithm based on the security mobile agent,in which mobile agents migrate in the net to get the network state and update the route table.It also builds a communication - trust table in every network node,using virtual space to ensure the agents＇ safety.A simple network model is also built on the Grasshopper platform to apply the algorithm.This algorithm improves the efficiency of routing algorithms,saves the network overhead,and has good prospects for the use.
