Fast authentication public key infrastructure for mobile ad hoc networks based on trusted computing

Public key certificate is the prerequisite for proving identity authentication between mobile ad hoc networks (MANET) nodes. However, for MANET's dynamic topologies and infrastructure-less, that bring the challengers for public key verification, similarly in hierarchical Public Key Infrastructure (PKI) in MANET In this paper, we propose a Fast Authentication Public Key Infrastructure (FA-PKI) for MANET, which does not require on-line centralize authority and certificate collection, can authenticate each other between MANET nodes. As the name implies, FA-PKI speeds up identity authentication process, while we employ Trusted Computing (TC) technology to enhance security in MANET Furthermore, we extend this scheme into Bridge PKI.
