Mobile ad-hoc Networking MANETS is a promising concept to provide flexible, adaptive, and reconfigurable architecture, cost effective solution.In the mobile ad hoc network security is the basic concern for network functions work properly.Routing is the corner stone in Mobile ad-hoc Networks, A lot of known vulnerabilities and security threats can be exploited to attack routing messages, so it is important to provide secure routing protocol for MANETs.In this paper, we present a secure extension for ad-hoc On Demand Distance Vector Protocol (AODV). The default routing protocol for MANETs. The proposed protocol ensures that discovery of the route between the nodes is functioning properly and securely, achieving mutual authentication between nodes, routing message integrity, generating a security key of data sent and exchanges it securely to ensure confidentiality and all of these are in one stage. By this we save in wireless band, resource consumption, preventing duplicate of authentication algorithms.
