Background: Security in WSNs is most significant because sensor nodes deployed are in an unattended environment, and the information communicated over insecure wireless channels. Therefore, there is a need to put enhanced security measures for securing sensor nodes as well as ensure secure transmission of information.
Objective: These resource-constrained networks suffer from various attacks namely, node clone attack, Sybil attack, DoS attack. In this paper, we propose a hybrid cryptography algorithm, which secure WSNs from node clone attack.
Method: The proposed algorithm uses combination of symmetric (AES) and asymmetric (ECC) cryptography techniques along with the hash function. Further, the proposed algorithm checks the integrity of messages during communication in the sensor network.
Results: The performance of the proposed hybrid algorithm examined through the various metrics like communication, computation, storage overheads. The comparison of results validate the efficiency of the proposed hybrid algorithm.
Conclusion: The proposed hybrid algorithm provide a secure and efficient solution to the energy inhibit sensor networks.
