一种安全的Ad Hoc On-demand路由协议

由于Ad Hoc网络固有的弱点,设计安全、有效的Ad Hoc路由协议是困难的.本文从新的角度设计了一个简单、安全的On-demand路由协议.在路径请求和响应阶段,源节点和目的节点的身份分别被隐藏,只有那些位于目的节点选择的最优路径上的节点可以获得完整的路由信息,从而产生有效的前向和反向路径.同时,一个公开的单向Hash函数可以利用隐藏的路由信息构建单向Hash链用于路由信息的认证,从而不需要预先的共享密钥.在一次路由计算中,只有源节点和目的节点需要进行一次非对称密码运算.

A Secure Ad Hoc On-demand routing protocol

Because of the inherent vulnerabilities, designing a secure and efficient ad hoc routing protocol is a challenge. In this paper, a simple and secure on-demand ad hoc routing protocol is proposed, in which some routing information is hided in the particular routing phase and only the nodes on the optimal route decided by the destination node can get the whole routing information. At the same time, an efficient one-way hash function is used for routing authentication. The hidden routing information and the public hash function can protect the routing protocol efficient. Only the source node and the destination node need operation of the asymmetric cryptographic algorithm once in a route computation.
