Abstract: In Mesh networks，the mobility of node and the multi-hop of data transmission，the quality and safety of routing protocol became the critical factors in weighing the performance of Mesh network.It is necessary to find more efficacious and safer routing protocol instantly，and it can adapt the topology change on network.Because the actual routing protocol of Mesh network didn’t consider the safety of the protocol itself.In this paper，a new scheme of secure multi-path routing protocol based on authentication is proposed.The safety mechanism is appended in the process of setting up the multi-path.The analysis shows that the routing algorithm can keep the safety of routing protocol on the base of supporting the balance of loading，enhancing the throughput in whole and increasing the ability of error tolerance.Beside，in this way，the node-disjoint between multi-paths can reduce the probability of path collapses and provide higher reliability for data transmission.

摘要： Mesh网络节点的移动性和数据传输的多跳性，使得路由协议的质量以及安全性成为衡量Mesh网络性能的关键因素，迫切需要一种能适应网络拓扑变化，高效、安全的路由协议。而目前针对Mesh网络的路由协议很少考虑到协议本身的安全性问题。提出了一种基于认证的节点分离安全多路径路由协议，在多路径的建立过程中加入了安全机制。分析表明，该路由算法在提供负载平衡、提高整体吞吐量、增加容错性的基础上能够很好地保证路由协议的安全性，而且多路径之间节点分离能够降低链路断开的概率，为数据传输提供更高的可靠性。
