Secure Communication Method Using Invitation Process in Mobile Ad Hoc Networks

摘要

The importance of security in mobile ad hoc networks has been recognized for many years, and many secure routing methods have been proposed in this field. This paper discusses major security attacks in mobile ad hoc networks and focused on resource exhaustion attacks as the most important security issue. We reviewed countermeasures including the methods that we proposed before for these attacks and propose a highly secure communication method that is based on a very efficient invitation process for handling new members. We evaluate the method from the viewpoint of implementation and make it clear that it is more useful than the methods that we proposed before as a countermeasure against resource exhausting attacks. We also study and evaluate the method from the viewpoint of stability and clarify that it makes the network stable on condition that it decreases the members who are expelled from the network when the attacker is found.
