摘要
针对移动代理路由安全问题,利用Hash函数单向性和迭代方法提出一种移动代理路由协议。用户主机通过Hash函数的单向性保证路由信息安全到达路由主机,路由主机之间根据Hash函数值的迭代进行交互认证。该协议的计算复杂度显著降低,特别是在大数据传输的情况下。采用常规方法和串空间模型方法分析并证明了该协议的安全性。
A new mobile routing protocol using Hash function and iterative method is proposed in this paper for solving mobile agent routing security problems. User hosts are able to ensure routing information transporting to the others securely by the unidirectional feature of Hash function, and verify each other by the iteration of Hash function. The analysis shows that the computational complexity of the routing protocol is drastically reduced, especially in the condition of transporting large number of data. The normal and the strand space models are adopted to prove the security of the protocol.
