Distributed Key Management Scheme for Mobile Ad-Hoc Network-A Survey

Ensuring security in Mobile Ad-hoc Network is a challenging issue. Mobile ad-hoc networks (MANET) are networks designed to operate in more volatile and rapidly changing environment. Establishing MANET security is entirely different from the traditional methods of providing network security. The two main approaches that are widely used in securing MANET are proactive and reactive. The first attempts to prevent security threats through various cryptographic key generation techniques. One among the various cryptographic techniques is distributed key management system for MANET security. This paper discusses various cryptographic techniques determined by researchers to provide MANET security. The efficient key distribution scheme for secure communication is essential to ensure network security. In addition, this paper discusses various key management schemes for secure wireless sensor network
