Securing mobile network prefix provisioning for NEMO based vehicular networks

The recently developed mobile network prefix provisioning (MNPP) enables a direct communication, i.e., Route Optimization (RO), between vehicular mobile routers (VMRs). However, without being secured, MNPP is vulnerable to various threats such as spoofing, replay, and wormhole attacks as well as location tracking. In this paper, possible threats to MNPP are identified with suggestions of security requirements. Then, three different security approaches (five different security mechanisms) for securing MNPP are introduced and compared.
