摘要：A Mobile Ad Hoc Network (MANET) due to its properties like nodes communicate in shared wireless medium without any centralized control suffers from major vulnerabilities. There are many threats in MANET due to maliciousness that using attacks disrupts the network because of insecure routing protocols like AODV, DSR which are created without considering security in mind. MANET due to its establishment in insecure environment makes it more vulnerable to attacks when a malicious node is further shared to provide different services. One example of such protocol is AODV which is used extensively and lot of research and development is in process. This paper deals with problems of AODV ( a reactive protocol) firstly, hop count and sequence no fields of its control packet which are is easily edited so it creates the possibility of abuse by malicious nodes. Secondly, routing updates are given in clear text form is also a security danger which reveals important information about the network topology This paper will propose a new approach to AODV to secure the routing. This paper uses pseudorandom cryptographic hash function MD6 in composition with Message Authentication Code (MAC) to secure AODV control packets like RREQ, RREP, RERR etc. which is a very less power consuming and effective solution for MANET. In this paper, we have also given the detail of Modified HMAC_MD6 for providing security in route discovery.
