A new method to secure RA-OLSR using IBE

In this paper, we propose a security schema for the Radio Aware Optimized Link State Routing (RA-OLSR) protocol. We consider the security vulnerabilities for RA-OLSR and apply mechanisms based on Identity Based Encryption (IBE). The motivation behind using the IBE-signature is that it eliminates the need to verify the authenticity of public keys. We have implemented the IBE technique to secure messages in RA-OLSR, namely Hello and TC messages. Through simulation experiments, we have evaluated the performance of our IBE-RA-OLSR in terms of delay and control overhead. Simulation results show that the IBE-RA-OLSR does not induce a long overhead compared to the original RA-OLSR protocol.
