An Authentication Scheme for Car-Home Connectivity Services in Vehicular Ad-Hoc Networks

Abstract

With the rapid development of technology, the Internet of Things (IoT) has been associated with various fields, such as smart home networks, intelligent traffic system (ITS), and so on. Vehicular ad-hoc networks (VANETs) can provide value-added services by roadside units (RSUs) for vehicles. Car-home connectivity can be defined as allowing drivers and passengers to remotely control smart appliances in the smart home while driving. The communication process between connected vehicles and smart appliances may cause personal information disclosure. To protect the security and privacy of communication, this paper proposes an authentication scheme for car-home connectivity services. The proposed scheme can protect the security and privacy of the communication process between the vehicle and the smart appliances and multiple third trusted authorities can cooperate to retrieve the identity of misbehaving users. The system analysis shows that the proposed scheme is efficient, secure, privacy-preserving, and easily deployable.
