Abstract
Mobile Adhoc networks (MANETs) is compendium of self-governing terminals, which basically interconnect and exchange information with each other and by establishing a multi-hop network for to maintain connectivity in a decentralized approach. In this research group key management approach is used, which further uses a symmetric group key for to communicate inside the cluster. Clusterhead is responsible for the generation of group key and is responsible for the communication of other nodes throughout a secure path which uses public key cryptography scheme. Encryption of messages is used for group keys to communicate inside the cluster and within the group for secure communication. In this research the results are shown through how to secure communication in MANETs through group key and clustering scheme minimizes the packet damages as compared to centralized approach. And also examine the system for proper authentication of public and private keys and evaluates the functioning of proposed methodology.
