Secure Routing Using Factual Correctness.

The routing protocols in use today operate on implicit trust among the different routers. Specifically, the distance vector routing (DVR) protocols compute routing tables in a distributed manner, based on this implicit trust. This trust model however fails to ensure the factual correctness of the routing updates, which is very critical for secure routing. We propose a neighbor update propagation model to ensure factual correctness and detect malicious activity by any subverted router. We also propose a secure DVR protocol based on this model using simple cryptographic primitives, and with minimal operational overhead. [ABSTRACT FROM AUTHOR]
