MANETs consist of a peer-to-peer, self-forming, self-healing network. Each device in MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. It is a shared wireless Medium, limited resource constraints and highly dynamic topology, MANET (Mobile Ad-hoc Network) is frequently established in insecure environment. In Military, government and Commercial Applications, which make them more Vulnerable to attacks. These attacks are initiated by sharing malicious nodes against different services of networks. The binding force in these networks is routing protocol, which is a common target of malicious nodes. MANET routing protocols are being developed without having security in mind. Ad-hoc on Demand Distance Vector (AODV) is on such widely used routing protocol) that is at present undergoing extensive research and development. AODV is based on distance vector routing, but hence the Updates are shared not on a periodic basis but on an as per demand basis. In AODV there must be two basic consideration kept in mind firstly to make the routing protocol secure and secondly to protect the data Transmission.In this paper we are presenting a secure SHA-DR2 Algorithm and practical security mechanism for securing the AODV routing protocol that protect against a number of attacks carried out in MANET. We will present the message digest with the security key mechanism to secure AODV messages which is very effective to offer best route from source to destination in terms of energy efficiency and security and less power consuming security solution for MANETS.
