Abstract: Secure communication over the Wireless Sensor Network (WSN) is one of today’s major concerns as the wireless communication medium suffers from a wide variety of security threats. Literature has suggested the multi-level key management protocol for establishing secure communication over WSN, where each transmission is established based on the availability of secured key. This work develops a key management protocol, namely Multi level Key Management (MLKM) protocol, for secure communication over the clustered WSN. The whole protocol is implemented in three stages, such as pre-deployment, key generation and key authentication and verification. In the first stage, the nodes are provided with the identity, and then the second stage uses the homomorphic encryption model to generate the necessary communication key. Finally, a mathematical model with multiple factors such as a hashing function, homomorphic encryption, dynamic passwords, profile sequence, random number, and EX-OR functions is developed in this work. The proposed MLKM protocol by authenticating the entities establishes the secured communication over the WSN. The entire work is compared and evaluated on the basis of several metrics with several states of art techniques. For communication overhead, detection accuracy, key memory storage and energy respectively, the proposed MLKM protocol achieved values of 0.122 kb, 0.929 kb, 2.332 kb and 14.586 joules.
