Enhanced Identity Based Encryption of Security for Wireless Sensor Network

Wireless Sensor Network (WSN) is defined as an ad hoc network setting that includes devices with limited resources for bandwidth, storage, computation time and energy. In the environment of WSN, security makes a substantial contribution to increased processing and energy in the nodes. Sensor nodes are used for remotely controlling network topology in dangerous environments. The secure data transmission over a network has garnered a lot of attention. The design of the key management scheme is required for future research because the mechanism of security management plays the vital role in WSN. Identity-based Encryption (IE) has experienced limited acceptance, owing to the complete confidence required of the private key generation utilizing Elliptic Curve Cryptography (ECC). The security in WSN has become a significant issue in the sensor network. The data get transformed from one node to another must be secured to avoid a data breach by any of the attackers. The link must be secured to ensure data efficiency and greater accuracy. This paper proposes the enhanced ECC algorithm for providing identity-based key encryption in cluster-based WSNs. A separate key generation concept has been proposed here for reducing the network complexity. The node-to-node has less number of key generations and the cluster head-to-sink node has a larger number of key generations. The outcome show that the suggested method holds well in minimizing the timing requirements for key generation, computation time is less, less energy consumption communication, and better packet-todelivery ratio.
