A Novel Authentication and Security Protocol for Wireless Adhoc Networks

Abstract

Mobile Ad-hoc Networks (MANet) are an assortment of wireless mobile nodes leading to flexible mobile networks, consequently eliminating constraint of any infrastructure and central access points. Due to enhanced utilization of a MANet, security has turned into a fundamental necessity because of its dynamic topology, inadequate processing capability, bandwidth confinements and high bit error rate etc. To present secure communication between wireless nodes, there is a requirement to construct multi-fence security and routing solutions to cope up with these challenges. In this paper, a mechanism named ‘novel secure authentication mechanism for communication in mobile ad-hoc networks’ is proposed which is derived from our previously published work [1]. The mechanism comprises two phases namely: authentication and confidential communication. In authentication phase, prior to joining the ad-hoc network, nodes are authenticated via acquiring security credentials from a server. In confidential communication phase, communication between two nodes is secured via making utilization of symmetric key cryptography for data encryption. Moreover, the stipulation of dual security in our scheme enables communication networks to be more secure against established security threats and vulnerabilities. Results demonstrate that validation of nodes before joining the ad-hoc network does not take excessive time. The results show that the proposed schemes is faster for new and existing nodes to join the network.
