The emerging vehicular communications will enable a variety of applications for safety, traffic efficiency, driver assistance and infotainment. Due to high vehicular speed, sporadic connection, limited communication range, and large volume of data that need to be transmitted, vehicular communications have the crucial requirements of fast authentication and encryption/decryption. This paper addresses...
"Vehicle-to-Grid" (V2G) power will be a new green energy scheme in which electric or plug-in hybrid vehicles communicate with the Smart Grid to sell demand response services by either delivering electricity into the grid or by throttling their charging rate. Due to high vehicular speed, sporadic connection, limited communication range, and large volume of data that need to be transmitted,...
Delay Tolerant Networks (DTNs) are a class of networks characterized by lack of guaranteed connectivity, typically low frequency of encounters between DTN nodes and long propagation delays within the network. As a result, the message propagation process in DTNs follows a store-carryand- forward manner, and the in-transit bundle messages can be opportunistically routed towards the destinations through...
Vehicular communications by means of exchanging safety message considerably reduces life and property damage. So securing this message is essential. In this paper, we focus on protocols based on a fixed key infrastructure that establish stronger security in comparison with dynamic structures. These protocols have some problems in terms of implementation issues. In effect, a very important issue is...
In this paper, we study group signature scheme for privacy preservation of a continually transmitting mobile vehicle. A moving vehicle transmits and receives different types of messages on the road. Such communication is a threat to the privacy of a vehicle as its communication can be used to link its identity to its physical entity. The change of size and nature of the neighborhood of a moving vehicle...
