Advanced Analysis of KTM and Security Issues in Mobile Ad Hoc Networks

Abstract

An ad hoc Network is a new generation of network offering unrestricted mobility without any underlying infrastructure. In this kind of network, all the nodes share the responsibility of network formation and management. This paper proposes a five-layer security architecture for ad hoc networks, that provides self organized distributed security, and authenticated, security aware routing. This model has been simulated and is found to provide security with negligible overhead? Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. The performance evaluation have their place in wireless network research, the current and future applications of the ad hoc networks have forced the research community to look at dependability and security aspects as eavesdropping and jamming. To develop suitable security solutions for such new environments, we must first understand how MANETs can be attacked. This chapter provides a comprehensive survey of attacks against a specific type of target, namely the routing protocols used by MANETs. We introduce the security issues specific to MANETs and present a detailed classification of the attacks/attackers against these complex distributed systems. Then we discuss various proactive and reactive solutions proposed for MANETs. It then addresses the possible solution to protect the security mechanism, which involves availability, integrity, authentication and non repudiation. These securities related issues are well addressed if one can provide methods that are pertinent for authentication, key distribution, and intrusion detection and rerouting in case of Byzantine failure in MANETS. Depending on the application context, a user may desire various security services such as authentication, integrity, non-repudiation, Confidentiality,(KTM) Key and Trust Management and access control.
