DYNAMIC KEY DISTRIBUTION MANAGEMENT USING KEY ESCROW BASED ECC ALGORITHM IN MANETS

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
