Dynamic High Secure Protocol for Mobile Adhoc Network

The working of MANET protocol, may compromise the security in it. In this paper, we propose a new key exchange method to improve the security of MANETs. In this proposed mechanism we send the key through the control packets instead data packets. By using this mechanism we can ensure that even if the intruder gets access to the data packet he cannot decrypt it because there is no key associated with the packet. Brute force attack also becomes infeasible because the packet is alive in the network for a less time.
