Merging clustering scheme in distributed certificate authority for ad hoc network

Ad hoc networking is a new wireless networking paradigm for mobile nodes. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, nodes rely on each other to keep the network connected. In this paper, we present a distributed certification authority based on cluster scheme for securing ad hoc network. It enhances the efficiency of partial distributed certificate authority (PDCA) and fully distributed certificate authority (FDCA).
