This paper includes developing framework for proxy based certificate Authority for MANET. Key management is a central aspect for security in mobile ad hoc networks. In mobile ad hoc networks, the computational load and complexity for key management is strongly subject to restriction of the node's available resources and the dynamic nature of the topology. PKI has been recognized as one of the most effective tools for providing security for dynamic networks. However, providing such an infrastructure in MANETs is a challenging task due to their infrastructure-less nature.
