Secure DVR Protocol Using Factual Correctness

The routing protocols in use today operate on implicit trust among the different routing elements. Specifically, the Distance Vector Routing (DVR) protocols compute updates and routing tables in a distributed manner, and consequently fail to ensure the factual correctness of the routing updates, which is very critical for secure routing. The authors propose a Neighbor Update Propagation (NUP) model to ensure factual correctness and detect malicious activity by any subverted router. They also propose a secure DVR protocol based on this model using simple cryptographic primitives, and with minimal operational overhead.
