SECURE KEY PAIRING TRANSMISSION USING SECRET AGREEMENT IN MULTI HOP WIRELESS SENSOR NETWORK

ABSTRACT There is no need for the key generating terminals to obtain correlated observations in channel. So, we build a secret agreement protocol between the Nodes. Source and Designation can communicate with Each other with Relay as the Intermediate Medium. Source and Designation Share their Primary and Secondary Keys to the Relay. Both the Keys are added together and made secret key by server and transmit the Corresponding Keys to both of them. This Key is used for Communication. Source selects the routes for data transmission to Designation based on checking neighbor node capacity. After key assignment and route selection, Source gives data with first half key to relay. If the keys are match means, relay sends the encrypted data to Source based on Digital Signature Algorithm. Source splits the data to three parts and sends the encrypted data to Designation through neighbor nodes on multiple routes. Designation sends the encrypted data with second half key to server. Then server check second half key of designation if both keys are match means, server sends the decrypted data to Designation. Suppose Hacker node receives and forwards the encrypted data to server for view the original data means, server checks the keys if both are mismatch means, it easily identify the Hacker node.
