On Demand Self-Organized Public Key Management for Mobile Ad Hoc Networks

A mobile ad hoc network MANET is a self-organized wireless network where mobile nodes can communicate with each other without reliance on a centralized authority. Security solutions for traditional networks are not suitable for MANETs due to the infrastructureless nature and the absence of centralized administration. Key management through accessing trusted authorities or centralized servers are infeasible for MANETs due to the absence of any infrastructure, frequent mobility, and wireless link instability. In this paper, the authors propose an on demand, self-organized, public key management for MANETs based on the existence of a web of trust between mobile nodes forming the network.
