A METHOD FOR OBTAINING SECURE AND EFFICIENT GROUP KEY OVER WIRELESS AD-HOC NETWORKS BASED ON A VIRTUAL SUBNET MODEL

Abstract
Today, mobile devices such as PDAs and notebooks etc are became most important in human life. A MANET is a mobile ad-hoc network which supports all types of communication such as unicast, multicast and “many-to-many” transmission. Until recently, efficient methods were not devised to generate group key for such groups. Generally, communication in wireless networks is, the risk of sensitive information being intercepted by unintended recipients is a real concern. So, MANETs require efficient and secure group communication. With the model, the groups are established as the forming of group keys. Our results show that this approach can completely satisfy the today’s needs of both security and efficiency for group communication.
