SFT: A Secure and Fast Transmission of Keys to Cooperative Group Communication and Key Management System
Y. Sheila, P. Harini, M. Tech · 2014
The problem of efficiently and securely broadcasting to a remote cooperative group occurs in many newly emerging networks. A major challenge in devising such systems is to overcome the obstacles of the potentially limited communication from the group to the sender, the unavailability of that of a fully trusted key generation center and the dynamics of the sender. Here the existing key management paradigms may cannot deal with these challenges effectively. A number of challenges such as efficient certificate distribution and revocation, avoidance of computation and communication bottlenecks, and reduction of the strong dependence on tamper-proof devices arise in existing protocols for securing VANETs. Communication messages in vehicular ad hoc networks (VANET) can be used to locate and track vehicles. While here the tracking can also be beneficial for vehicle navigation, where it can also lead to threats on location privacy of vehicle user. In this paper, we are addressing the problem of mitigating unauthorized tracking of vehicles based on their broadcast communications, where to enhance the user location privacy in VANET. In this paper we propose a novel scheme for both secure and fast transmission of keys to cooperative groups
