Abstract
In recent years, with the rapid increasing of mobile equipments, the research topics about mobile ad hoc networks (MANETs) become attractive. Earlier studies aimed at proposing protocols for solving some fundamental problems such as routing. However, the features of MANETs make it more vulnerable than traditional wireless networks. To get to the bottom of these security problems, the mobility of each mobile host is the fundamental factor.
In this thesis, we focus on how to provide authentication services in MANETs. A new concept which names “locality” is introduced into our authentication architecture to model the movement of all mobile hosts in the MANET. This mobility model with locality property is called “mobile locality model” in our approach. The basic idea of “mobile locality model” is that each mobile host has high probability for roaming at a fixed and small region of whole MANET and each mobile host in the same locality can monitor the behavior of each other more easily. Based on “mobile locality model”, we present a practical and efficient distributed public key management system for providing secure communication between mobile hosts. Our solution includes group-based network model and trust model which allow mobile hosts to exchange certificates efficiently and rate each other with a trust evaluation metric. Finally, we perform an overall evaluation of our solution through simulation to demonstrate the effectiveness of the proposed scheme.
