Abstract
Recently, the progression in Internet of Thing (IoT) has extensively influenced the model of wireless networking. As numerous wireless devices were emerged, the new Medium Access Control (MAC) and routing protocols has been introduced for assuring the end-to-end network efficiency. This paper aims to focus on the IEEE 802.15.4 MAC standards, where the security field is included in MAC header. The sensitive data security authentication on this MAC header is completely based on the method with the introduction of optimum authentication key using partially homomorphic encryption named ElGamal public key cryptosystem. More importantly, in this work, the ElGamal public key cryptosystem for securing IoT data is progressed by generating the optimal private key as well. For this optimal selection of key, this paper aims to establish a new hybrid optimization algorithm that hybrids the concept of Lion Algorithm (LA) and Cuckoo Search Algorithm (CS) named Cuckoo Mated-Lion Algorithm (CM-LA). Finally, the performance of the proposed working strategy is compared over other state-of-the-arts models by concerning various attacks, convergence and key sensitivity analysis, respectively.
