A biometric authentication approach for high security ad-hoc networks

Abstract

With the rapid development of wireless technology, various mobile devices have been developed for military and civilian applications. Defense research and development has shown increasing interest in ad-hoc networks because a military has to be mobile. Peer-to-peer is a good architecture for mobile communication in coalition operations. Since there is no need for a dedicated server, users can dynamically route information through the network to anywhere at any time. However, this architecture brings a new challenge in user authentication, which is normally carried out in an authentication server that is absent in ad-hoc networks. In this paper, a biometric authentication model is presented to enhance information security in ad-hoc networks. Using this model, a peer is authenticated with biometrics when joining an existing group even without the presence of an authentication server.
