Abstract

In the Information and Communication (ICT) Era, the data transmission through wireless communication has become most proficient and rapid tool around the world. IEEE standard 802.11for WLAN has been meeting out the communication prospect in any organization. A Mobile Adhoc Network (MANET) is defined as the collection of independent mobile nodes that can communicate with each other via radio waves. In mobile ad hoc networks, the key distribution is the main constraint in data transmission. For secure group based data transmission in the distributed environment, a secret key has to be shared among the users for the secured data transmission. For establishing efficient key distribution and management, a novel dynamic group secret key management is introduced. For secure data communication,a group secret key must be shared by all group members. This group secret key should be updated when the existing group members are leaving the network or new members are entering into the existing network. In this paper, we propose an efficient group secret key agreement procedure called Key distributed management protocol which is based on Elliptic curve cryptography. Here the model of scheme is to divide a large group into several subgroups, each maintaining its subgroup secret keys to control the subgroup and managing many subgroups using KEY escrow Based Elliptic Curve Cryptography management algorithm. In KEYBECC, we develop two protocols namely, Subgroup Secret Key Generation (SSKG) and Group Secret Key Generation (GSKG) based on ECDH for subgroups and outer groups respectively. These subgroup keys and group keys should be changed when there are membership changes (such as when the current member leaves or the new member joins). In the paper, we propose and implement a new methodology for dynamic key distribution. We simulate the environment for mobile networks with the proposed algorithm named Enhanced Key Escrow Based ECC (KEYBECC) with comparison of the traditional algorithms prevailing for MANETs. Compared to the existing approaches, KEYBECC demonstrates advanced key distribution features with better throughput efficiency without compromising on communication overhead and storage cost. From the simulation analysis, the proposed dynamic group key agreement protocol performs well for the distributed key establishment problem in mobile ad hoc network in terms of throughput efficiency, communication overhead and storage cost
