Security Server-Based Architecture for Mobile Ad Hoc Networks

Abstract

A Mobile Ad hoc Network (MANET) is receiving a great attention by different communities (e.g. military and civil applications) thanks to its self-configuration and selfmaintenance potential. Securing a MANET is a very critical matter as it is vulnerable to different attacks and also it is characterised with no clear line of defence. Since any security solution relies on a particular trust model, there are different types of trust models that could suit MANETs. This paper present a design of security architecture based on the hybrid trust model. It consists of a set of servers (i.e. a Central authority Server (CAS), Threshold Authority Servers (TASs) and Delegated Authority Servers (DASs)) emulating certification authorities. Our security architecture caters for improving services availability and utilisation.

“…The "openness" of the network architecture and its dynamic network topology imposes restrictions on MANET [2]. In MANET, all devices have an equal status and are free to communicate with one another within a circle.…”
