An empirical study of a cryptographic scheme for secure communication in mobile Ad Hoc networks

Abstract

The design and implementation of a cryptographic scheme in a mobile ad hoc network (MANET) is highly complicated than the traditional networks. This is due to several reasons, like—unavailable central infrastructure services, periodic movable nodes, wireless link unsteadiness, and possible network separations. In this paper, we present a cryptographic key management scheme for secure communications in ad hoc networks. The scheme transmits the data in the presence of security attacks. The scheme provides the scalability of nodes and storage space wherein the nodes makes use of more than one key pair to encrypt and decrypt the messages. The scheme has been executed in Java programming language and empirically valued its efficiency via performance and security assessments. The simulation outcome has shown that the proposed scheme opposes against selfish nodes and takes less key storage space than traditional schemes. The scheme also satisfies the secure communication requirements.
