Providing security for Dynamic Cluster based Mobile Ad-hoc networks (MANET) is a vital task to improve network security with less compromising mobility and with reduced dedicated Data occupancy. Key generation, distribution and authentication are major tasks of a key management system.
A flexible and strong model is required to handle key management since dynamic ad-hoc networks are more prone to many kinds of hacking activity. In this paper a new procedure is implemented using Chinese remainder Theorem based Key-management (CRT-KM) and it is compared with one existing ID-Based Multiple Key Management system (IMKM). The performances are compared interms of parameters like mobility, Overhead message; security and power consumption.
