Wireless sensor network is a cluster of sensors with finite resources that integrate in order to attain a common goal. Because of their working nature, it is vulnerable to different kinds of novel attacks. Diagnosing the attack of node replication has turn into an obligatory analysis in sensor network security, and mapping detection strategy against node replication attack includes various menacing problems and challenges. This work concentrates on authenticating key while distributing in order to secure network. A scheme is introduced namely Credible Node Selection with Enhanced Protection using Key Authenticate (CNSEP-KA). In this scheme, every node in network must confirm adjacent location of another node with help of message authentication code computed on relative public key using keys acquired from encrypted beacons transmitted by anchor nodes before initiating pairwise key between two nodes. The performance analysis of proposed CNSEP-KA shows the increases transmission of data, decreased rate of packet loss, and minimized energy consumption comparing to existing techniques.
