Optimizing Energy Efficiency and Security in Wireless Sensor Networks with a Hybrid HF-ECC

Numerous distinct categories of businesses take advantage of “Wireless Sensor Networks (WSNs)”. Interfering with “Sensor Node (SN s)” and eavesdropping on communications are two possible attacks. Physically placed SN s provide an additional opportunity for hackers to alter the information being transmitted or establish unauthorized connections over the WSN network. Verifying the route and encrypting information transmitted across connected SN s are a couple of steps toward WSN privacy. The network's SN s must additionally possess an authentication key for encrypting and decrypting processes. As a result, proper key administration is crucial for WSN security. Secured and energy-effective transfer of information within WSN needs to obtain suitable key organizations in environments with limited resources. There are several security concerns with existing “Elliptic Curve Cryptography (ECC)” techniques, including their cost of computation and susceptibility to multiple assaults. A “Hash- Function (HF)” relied on MAC authenticating protocol and an ECC built around “Secrecy Connectivity Probability (SCP)” is proposed in this paper as a hybrid (HF-ECC) protocol. The originating SN uses the HF for authenticating against its neighboring SN s using the MAC Key, which produces pre- distribution keys, once the SNs are deployed throughout the WSN region. For determining the key, each SN needs to perform broadcasting with its identity; this will get them accessibility to the self-organized through a secure process. Upon route establishment, the ECC began working in the origin SN for encryption of the information ahead of transmission. Whenever the message that was encrypted arrives at the recipient SN, the ECC decrypts it. Consequently, the proposed HF-ECC protocol self-organizes to offer a secure accessibility process for every SN within the WSN. In comparison to the existing ECC, the proposed hybrid (HF-ECC) protocol outperforms it regarding both security and energy efficiency, according to the comprehensive evaluation.
