MANET is a unique application in Ad hoc network which have no central coordinator or any central controller to manage the network. This network is formed automatically with wireless devices when demand arise for the routing the packets, without any prior infrastructure or base station. The main fact of the MANET is the mobility of the nodes and also the wide distribution and open medium makes them vulnerable to malicious attackers. In this paper, symmetric key approach is used between the trust users. This emerges the challenges in key management and also to overcome the existing key management due to unavailability and trustworthiness. A novel key management scheme is proposed which firmly shares the data along with the session keys between the users. This key management uses a self-configured protocol which helps to originate the network with secure services. The protocol uses lot of functionalities for initializing the node, route establishment and key sharing which is operated without the usage of external entities. Also, if any unauthorized members collude, they can't extract any confidential information during communication. Each and every node in a network is verified using digital signatures for authentication purpose. In order to Share the key, extra route packets are not needed. This paper lessens the usage of key pairs which limits the order of communication in the network. The proposed scheme also shrinks the cost of communication as well as limits the usage of resources.
