摘要:

An Ad Hoc network is a multi-path autonomous system comprised of a group of mobile nodes with wireless transceivers. In this paper, we first review the present research in key management in Ad Hoc networks. Then, by considering the characteristics of Ad Hoc networks in which the free movement of nodes can lead to a variety of topological changes, especially network separation and convergence, we propose a new key management scheme based on a combination of techniques, such as hierarchical topology structure, virtual CA (certification authority), offline CA and certificate chain. We show that the proposed scheme would improve key management in security, expandability, validity, fault tolerance and usability. © Springer-Verlag Berlin Heidelberg 2006.
