Dependable Propagating Routing Information in MANET

摘要

The dynamic topologies and membership in MANET make it difficult to use conventional routing protocol for propagating trusted routing message between individual nodes. However, it is the most important thing to implement the secure communication in MANET that how to propagate routing message dependably to discover the secure shortest paths. This paper defines a trusted routing discovery model, MARD, which proposed to authenticate the protocol participants in order to prevent the malicious node from providing secure shortest paths, negotiate one times session keys to encrypt the communication between the source and destination nodes by using the routing discovery mechanism at the same time. In the end, the analysis shows that secure goals have been achieved.
