OLSR is one of the efficient routing protocols for MANETs, which is identified by IETF and assumes that all nodes are trusted. However, the OLSR is known to be vulnerable to various kinds of malicious attacks in hostile environment. In this paper, we propose a new security enhancement mechanism by adding security features to the existing the OLSR protocol. The security features included are based on authentication checks of information injected into the network, mutual authentication between two nodes as well as more advanced techniques such as authentic route confirmation ticket which regulates the behavior of nodes to prevent from internal attacks i.e. node misbehavior attack. The main contribution of our approach is to allow only legitimate nodes to participate to establish secure route rather than trying to detect adversary nodes after their involvement in the routing protocol.
