The growth of wireless sensor networks (WSNs) in the last few years, enhances the use, efficiency, and accuracy of a large number of applications such as defense, habitat monitoring, industrial, and many more. The performance of WSNis largely affected by the security, as large numbers of security attack are happening on the WSN. Therefore, it is necessary to have a security solution to use theWSN proficiently. The objective of this paper is to address the security problem of WSN by proposing the key management mechanism to establish the secure link for communication. The paper proposes the cluster-based key management technique based on hash key mechanism. The mechanism considers the key establishment and verification at two levels, one at onehop distance and the other at multi-hop destination. The proposed work is evaluated by considering the varying number of attackers in the network. The mechanism shows reduced packet lost rate and energy consumption as compared with one-hop key management solutions, by making the tradeoff of delay. The results shows the improvement in packet loss rate i.e., without any solution, if attack happens obviously the attack performance reduces with an increase in pack loss rate and after applying the solution, the packet loss rate is reduced.
