Dynamic nature of the MANET has wide variety of opportunities for the innovative researchers to think and propose varied solutions to upgrade the communication system. Because of the dynamic nature of the environment, security measures play a major role. The same nature is considered as strength of the environment in this paper. Resolutions of the Passive attacks in the MANET AODV routing is one of the challenging requirement corresponding to security aspect of the environment. In this regard, the proposed paper is trying to introduce a revolutionary key distribution algorithm by adding few columns into existing AODV routing table. Also the paper is verifying the performances of the regular AODV and the proposed algorithmic framework corresponding to end-to-end delay, throughput and packet drop parameters of the network. Network Simulator 2 is employed for the parameter estimation of the proposed and existing systems.
