基于SEND协议的安全路由认证机理与方法

Mechanism and method of secure routing authentication based on SEND

通过对现有路由认证手段进行分析,提出了新的路由认证概念,并设计了3个阶段的安全路由认证算法,重点针对通信路径建立阶段和回溯验证阶段,实现了数据报依预设可信路由传输,并使通信端节点能够通过独立于可信第三方对传输数据报的路由进行核验,获取通信路径上路由器的信息。

The existing method of routing authentication is analyzed and a new concept of routing authentication is proposed. A three-stage secure routing authentication algorithm is designed, especially the one of communication path establishment stage and the back-tracing validation stage, for datagram to be transferred by trusted touters. The communication receiving end nodes can also verify the routers which have transferred the datagram earlier independently without a third party, and obtain the information of routers on the communication path.
