Synergizing Roadway Infrastructure Investment with Digital Infrastructure for Infrastructure-Based Connected Vehicle Applications: Review of Current Status and Future Directions
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.The safety, mobility, environmental and economic benefits of Connected and Autonomous Vehicles (CAVs) are potentially dramatic. However, realization of these benefits largely hinges on the timely upgrading of the existing transportation system. CAVs must be enabled to send and receive data to and from other vehicles and drivers (V2V communication) and to and from infrastructure (V2I communication). Further, infrastructure and the transportation agencies that manage it must be able to collect, process, distribute and archive these data quickly, reliably, and securely. This paper focuses on current digital roadway infrastructure initiatives and highlights the importance of including digital infrastructure investment alongside more traditional infrastructure investment to keep up with the auto industry's push towards this real time communication and data processing capability. Agencies responsible for transportation infrastructure construction and management must collaborate, establishing national and international platforms to guide the planning, deployment and management of digital infrastructure in their jurisdictions. This will help create standardized interoperable national and international systems so that CAV technology is not deployed in a haphazard and uncoordinated manner
Security of 5G-V2X: Technologies, Standardization and Research Directions
Cellular-Vehicle to Everything (C-V2X) aims at resolving issues pertaining to
the traditional usability of Vehicle to Infrastructure (V2I) and Vehicle to
Vehicle (V2V) networking. Specifically, C-V2X lowers the number of entities
involved in vehicular communications and allows the inclusion of
cellular-security solutions to be applied to V2X. For this, the evolvement of
LTE-V2X is revolutionary, but it fails to handle the demands of high
throughput, ultra-high reliability, and ultra-low latency alongside its
security mechanisms. To counter this, 5G-V2X is considered as an integral
solution, which not only resolves the issues related to LTE-V2X but also
provides a function-based network setup. Several reports have been given for
the security of 5G, but none of them primarily focuses on the security of
5G-V2X. This article provides a detailed overview of 5G-V2X with a
security-based comparison to LTE-V2X. A novel Security Reflex Function
(SRF)-based architecture is proposed and several research challenges are
presented related to the security of 5G-V2X. Furthermore, the article lays out
requirements of Ultra-Dense and Ultra-Secure (UD-US) transmissions necessary
for 5G-V2X.Comment: 9 pages, 6 figures, Preprin
Software-Defined Network-Based Vehicular Networks: A Position Paper on Their Modeling and Implementation
There is a strong devotion in the automotive industry to be part of a wider
progression towards the Fifth Generation (5G) era. In-vehicle integration costs
between cellular and vehicle-to-vehicle networks using Dedicated Short Range
Communication could be avoided by adopting Cellular Vehicle-to-Everything
(C-V2X) technology with the possibility to re-use the existing mobile network
infrastructure. More and more, with the emergence of Software Defined Networks,
the flexibility and the programmability of the network have not only impacted
the design of new vehicular network architectures but also the implementation
of V2X services in future intelligent transportation systems. In this paper, we
define the concepts that help evaluate software-defined-based vehicular network
systems in the literature based on their modeling and implementation schemes.
We first overview the current studies available in the literature on C-V2X
technology in support of V2X applications. We then present the different
architectures and their underlying system models for LTE-V2X communications. We
later describe the key ideas of software-defined networks and their concepts
for V2X services. Lastly, we provide a comparative analysis of existing
SDN-based vehicular network system grouped according to their modeling and
simulation concepts. We provide a discussion and highlight vehicular ad-hoc
networks' challenges handled by SDN-based vehicular networks.Comment: 14 pages, 3 figures, Sensors 201
Recent Developments on Security and Privacy of V2V & V2I Communications: A Literature Review
In the recent years Intelligent Transportation Systems and associated technologies have progressed significantly, including services based on wireless communications between vehicles (V2V) and infrastructure (V2I). In order to increase the trustworthiness of these communications, and convince drivers to adopt the new technologies, specific security and privacy requirements need to be addressed, using Vehicular Ad Hoc Networks (VANETs). To maintain VANET′s security and eliminate possible attacks, mechanisms are to be developed. In this paper, previous researches are reviewed aiming to provide information concerning matches between an attack and a solution in a VANET environment
"On the Road" - Reflections on the Security of Vehicular Communication Systems
Vehicular communication (VC) systems have recently drawn the attention of
industry, authorities, and academia. A consensus on the need to secure VC
systems and protect the privacy of their users led to concerted efforts to
design security architectures. Interestingly, the results different project
contributed thus far bear extensive similarities in terms of objectives and
mechanisms. As a result, this appears to be an auspicious time for setting the
corner-stone of trustworthy VC systems. Nonetheless, there is a considerable
distance to cover till their deployment. This paper ponders on the road ahead.
First, it presents a distillation of the state of the art, covering the
perceived threat model, security requirements, and basic secure VC system
components. Then, it dissects predominant assumptions and design choices and
considers alternatives. Under the prism of what is necessary to render secure
VC systems practical, and given possible non-technical influences, the paper
attempts to chart the landscape towards the deployment of secure VC systems
Secure Vehicular Communication Systems: Implementation, Performance, and Research Challenges
Vehicular Communication (VC) systems are on the verge of practical
deployment. Nonetheless, their security and privacy protection is one of the
problems that have been addressed only recently. In order to show the
feasibility of secure VC, certain implementations are required. In [1] we
discuss the design of a VC security system that has emerged as a result of the
European SeVeCom project. In this second paper, we discuss various issues
related to the implementation and deployment aspects of secure VC systems.
Moreover, we provide an outlook on open security research issues that will
arise as VC systems develop from today's simple prototypes to full-fledged
systems
