Group key management is one of the basic building blocks in collaborative and group-oriented applications in Mobile Ad Hoc Networks (MANETs). Group key establishment involves creating and distributing a common secret for all group members. However, key management for a large and dynamic group is a difficult problem because of scalability and security. Dynamical changes in network’s topology causes feeble conviction relationship among the nodes in the network. In MANETs a mobile node operates as end terminal as well as an midway router. Therefore, a multi-hop situation occurs for communication in MANETs; where in between source and destination there may be one or more malicious nodes. In this paper, we proposed a key management scheme. We assume that MANETs is alienated into groups having a group leader in each group. Group leader has accountability of key management in its group. Proposed key management scheme is a decentralized method that does not need any Trusted Third Party (TTP) for key management. In proposed key management scheme, both a new node and group leader validates each other equally before joining the network
