Council-based Distributed Key Management Scheme for MANETs

Mobile ad hoc networks (MANETs) have been proposed as an extremely flexible technology for establishing wireless communications. In comparison with fixed networks, some new security issues have arisen with the introduction of MANETs. Secure routing, in particular, is an important and complicated issue. Clustering is commonly used in order to limit the amount of secure routing information. In this work, we propose an enhanced solution for ad hoc key management based on a cauterized architecture. This solution uses clusters as a framework to manage cryptographic keys in a distributed way. This paper sheds light on the key management algorithm for the OLSR protocol standard. Our algorithm takes into account the node mobility and engenders major improvements regarding the number of elected cluster heads to create a PKI council. Our objective is to distribute the certification authority functions for a reduced and less mobile cluster heads that will serve for keys exchange.
