Paper Abstract:	This paper proposes a novel secure mechanism for managing the digital certificates in WMANETs. Based on our defined architecture for WMANETs, we will take the case where WMANET is operating in an area covered by other infrastructure-based wireless networks such as cellular systems or WLANs. We define two different algorithms for two different scenarios. The first algorithm manages the digital certificates in the case all the ad hoc nodes are covered by other infrastructure-based wireless networks. This algorithm is based on the hierarchal trust model used in PKI to provide high level of security, availability and well management certification service. The second algorithm will take the assumption that some of the ad hoc nodes are covered by other wireless networks. In this case, both the certification authority characteristics of PKI and web of trust are combined. The ongoing research attempted to adapt one of these two approaches to WMANETs. The proposed solution will solve the shortcomings of applying one of the two approaches separately to WMANETs and enhance the level of security by combining their features. The novel mechanism is still a fully distributed, provides a high level of security, availability, flexibility and efficiency key management services for WMANETs. Graph theory will be used to represent our security system, study its performance and demonstrate its effectiveness.
