Trust Establishment in Ad Hoc Networks by Certificate Distribution and Postponed Verification

Free registration required

Executive Summary

Trust establishment in wireless ad hoc networks is a challenge because of its unique characteristics. These include the lack of a central authority and the autonomous, dynamic nature of these networks which result in poor connectivity and routing failure. Security can be provided by a certificate based model but key management is a difficulty in wireless ad hoc networks. A key management scheme is proposed which realizes certificate distribution and verification. The key management scheme occurs in an on-demand, fully distributive, wireless ad hoc network environment, establishing trust on the routing layer exclusively. Trust and route establishment are achieved simultaneously with reduced dependency between the security and routing mechanisms.
