MANET is the mobile ad-hoc network. It is the wireless network having various mobile nodes. Because it is infrastructure less network having various issues. Major Issue is of security. Due to the security vulnerability mobile node can be attacked. Or even there is a attack on the communicated message. So that no illegal person can access the data. While data is being shared between two authenticated persons. In between relay can read the message or even destroy the message. Under such situation the network authenticity is maintained using hash function. In current research the hash SHA-512 is being used for CSA and CPA. Under both the techniques three different scenarios are being builded. These scenarios are under three different protocols like AODV, DSDV, DSR. Under all the protocols the proposed technique has better results in terms of Latency, Energy, Time of Connection. All the parameters are having better results compared to the base technique of CSA. So proposed technique CPA has better results under all the protocols.
