ENSURE SECURE COMMUNICATION IN AD HOC NETWORK

GAURAV VISHWAKARMA

Abstract


Abstract-- An ad-hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. It is a mobile network of new era. In such an environment, it may be necessary for one mobile host to enlist the aid of other host in forwarding a packet to its final destiny, due to the restriction in the (limited area) range of each mobile hosts wireless transmission .the military tactical, highway traffic & other security-sensitive operation are still the main application of ad-hoc network, although there is a trend to adopt ad-hoc networks for commercial uses due to their unique properties .one main challenge in the design of these network is their vulnerability to security attacks. In this paper, we study the threat an ad-hoc network faces and security goals to be achieved. I identify the new challenge posed by this new networking environment & explore new approaches to secure its communication. In this network as we already provide numbers of security features like secrecy, reliability , cryptography etc., but the problem is not only up to this , the main thing is the members in the network are globally authentic or not. If we globally authenticate the user in the network then we can ensure the communication in the network is secure communication.
