IEEE Project Abstract

The modern intelligent transportation system brings not only new opportunities for vehicularInternet of things (IoT) services but also new challenges for vehicular ad-hoc networks (VANETs). Apartfrom enhanced network performance, a practical and reliable security scheme is needed to handle the trustmanagement while preserve user privacy at the same time. Emerging 5G mobile communication systemis viewed as a prominent technology for ultra-reliable, low-latency wireless communication services. Furthermore,incorporating software defined network (SDN) architecture into the 5G-VANET enables globalinformation gathering and network control. Hence, real-time IoT services on transportation monitoringand reporting can be well supported. Both pave the way for an innovative vehicular security scheme.This paper investigates the security and privacy issue in the transportation system as well as the vehicularIoT environment in SDN-enabled 5G-VANET. Due to the decentralized and immutable characteristics ofblockchain, a blockchain based security framework is designed to support the vehicular IoT services, i.e.,real-time cloud-based video report and trust management on vehicular messages. This paper explicitlyillustrates the SDN-enabled 5G-VANET model as well as the scheduling procedures of the blockchainbasedframework. Numerical simulation results also show that malicious vehicular nodes or messages canbe well detected while the overhead and impact on the network performance are acceptable for large-scalescenarios. Through case studies and theoretical analysis, we demonstrate our design substantially guaranteesa secure and trustworthy vehicular IoT environment with user privacy preserved.
