Abstract: Mobile ad hoc network (MANET) is an autonomous system of mobile nodes, which are connected each other through wireless links. A mobile ad hoc network (MANET) is a type of self configuring network and have dynamic topology. Since each node in MANET is free to move independently, they can change their links to other nodes frequently. Secure communication among nodes in mobile ad hoc networks is a major concern. Many key management (KM) schemes and protocols have been evolved in past years, but developing fundamentally secure key management scheme for dynamic MANET's is still an open research problem. In this paper, first we reviewed some significant existing KM schemes and compared based on various criterias and design parameters. Next, we have proposed a scheme for pairwise key agreement with updation of key pre-distribution shares while new nodes are getting added to the MANET. Further, we have given our simulation results and performed a comparative analysis based on different simulation's parameters. Future research issues are also discussed at the end of the paper.
