5G-VRSec: Secure Video Reporting Service in 5G Enabled Vehicular Networks. (25th July 2017) - Yoo, Sang Guun
Abstract : Despite an imminent arrival of the 5G communication technology, there are only a few research works done using such technology in the field of vehicular networks. One of the pioneers in proposing a service for 5G enabled vehicular networks is the Eiza-Ni-Shi Scheme. In such scheme, the authors present an innovative system model for 5G vehicular networks that enables a secure real-time video reporting service with privacy awareness. Even though the proposed service is very important since it aims to improve the road safety, it cannot be considered secure enough. This work found that the scheme has serious security flaws and functionality limitations. First, it is vulnerable to Department of Motor Vehicles and Law Enforcement Agency impersonation attacks, it allows forged video upload, there is no separation of responsibilities between Law Enforcement Agency and trusted authority, and it is susceptible to privileged insider attack. In addition, it does not contemplate the management of multiple geographic/administrative regions (multiple trusted authorities) which is important in real implementations. In this situation, the present work proposes an extended scheme that eliminates the identified security flaws and implements new features that make the implementation across several geographic/administrative regions possible.
