Security in WSNs is the most significant because sensor nodes deployed are in an unattended environment, and the information is communicated over insecure wireless channels. Therefore, there is a need to put enhanced security measures for securing sensor nodes as well as ensure secured transmission of information.

These resource-constrained networks suffer from various attacks namely, node clone attack, Sybil attack, and DoS attack. In this paper, we proposed a hybrid cryptography algorithm, which secured WSNs from node clone attack.

The proposed algorithm uses a 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.

The performance of the proposed hybrid algorithm was examined through the …
