Abstract
A Mobile Ad Hoc Network (MANET) is an autonomous network developed using wireless mobile nodes without the support of any kind of infrastructure. In a MANET, nodes can communicate with each other freely and dynamically. However, MANETs are prone to serious security threats that are difficult to resist using the existing security approaches. Therefore, various secure routing protocols have been developed to strengthen the security of MANETs. In this paper, a secure and energy-efficient routing protocol is proposed by using group key management. Asymmetric key cryptography is used, which involves two specialized nodes, labeled the Calculator Key (CK) and the Distribution Key (DK). These two nodes are responsible for the generation, verification, and distribution of secret keys. As a result, other nodes need not perform any kind of additional computation for building the secret keys. These nodes are selected using the energy consumption and trust values of nodes. In most of the existing routing protocols, each node is responsible for the generation and distribution of its own secret keys, which results in more energy dissemination. Moreover, if any node is compromised, security breaches should occur. When nodes other than the CK and DK are compromised, the entire network’s security is not jeopardized. Extensive experiments are performed by considering the existing and the proposed protocols. Performance analyses reveal that the proposed protocol outperforms the competitive protocols.

Summary
Mobile Ad Hoc Networks (MANETs) are autonomous networks developed using wireless mobile nodes without the support of any kind of infrastructure. In a MANET, nodes can communicate with each other freely and dynamically through radio frequencies [1,2,3]. MANETs allow mobile users to communicate with one another when permanent infrastructure is not available or possible [4]. The routes in a MANET are frequently unable to work correctly due to external noise, transmission interference, and mobility. The development of the internet in recent years has considerably improved MANETs’ usage in various critical applications. MANETs are extensively utilized to build Internet of Things (IoT)-based smart networks [5,6]. The requirements for safety and consistency in these types of networks should be thoroughly re-evaluated
