<p> In the present generation, wireless sensor networks find their application in various fields such as, the building automation systems, body sensor networks, pollution monitoring, earthquake sensing, navigation guidance, temperature, and other variables monitoring where the human intervention is challenging and impossible. The wireless sensor nodes are deployed in different places for the continuous monitoring of the physical parameters of interest and transmit the information to the base station. For any wireless sensor network, data confidentiality, efficiency and data security are the basic requirements. A protocol, which is used to maintain a wireless network, should be able to adapt to changes in the environment and it should possess the capability to differentiate the malicious nodes from genuine nodes. Along with lower computational power and storage. The Zero Knowledge Protocol, which is based on the identity technique, is proposed in this work. Its flexible secret/private key generation technique along with the two-way authentication mechanism helps to attain the requirements of any wireless sensor network. The increased number of a challenging question with a simultaneous reduction in the number of rounds of authentication process helps to reduce the computational overhead and storage, making it an efficient protocol. Our simulation results using the Network Simulator (NS2) application prove the security and authentication of the proposed ZKP protocol in wireless network environment.</p>
