Recent Advances and Challenges in Security and Privacy for V2X Communications

Abstract

In recent studies, vehicular networks have been considered as a promising solution to achieve better traffic management and to improve the driving experience of drivers. In vehicular networks, vehicle-to-everything (V2X) services, e.g. onroad traffic information exchange and location-based services, are provided to facilitate road safety for vehicles and traffic management for the relevant authorities. Dedicated Short Range Communications is specifically designed for V2X communications, and recently the cellular network has shown great potential to support V2X with better performance and more applications. Due to the wireless nature of V2X communications, how to secure V2X communications and guarantee the privacy of users are great challenges that have hampered the implementation of vehicular services. Many solutions have been proposed by researchers in last two decades. In this paper, we present a comprehensive survey on the state-of-the-art solutions concerning security and privacy for V2X communications. For security, detailed discussions on cryptography based schemes and trust based schemes are provided. For privacy, we summarize and compare general solutions in preserving identity privacy and location privacy. Cellular based V2X communications have shown many advantages over DSRC, and the oncoming fifth-generation cellular technology is going to provide more possibilities to V2X. Thus, security architectures and solutions for cellular based communications are also illustrated and discussed. Finally, we summarize the remaining challenges and point out future research directions.

A Survey on the Current Security Landscape of Intelligent Transportation Systems

“…Lu et al [18] provide a comprehensive security analysis in the field of vehicular networks with a special emphasis on anonymous authentication schemes, used to protect the privacy of vehicle users, and trust management models. Similarly, Huang et al [19] provide an in-depth review of the state-of-the-art solutions concerning security and privacy for V2X communications. However, both contributions did not cover new emerging security solutions (e.g., machine learning-based defense mechanisms and 5G-V2X security technologies).…”

A Noise-Shaped Signaling Method for Vehicle-to-Everything Security

“…With the commercialization of the V2X, the importance of security has long been emphasized [20]. IEEE 1609.2 standard defines formats of the secure message and security processing of the DSRC protocol [21].…”

İtibar Sistemleri Temelli Akıllı Trafik Sistemleri Sistemi

“…Son yıllarda ATS'lerde genel güvenlik ile ilgili sorunların çözümü için farklı akademik çalışmalar yapıldı [13][14][15][16][17][18][19]. [13]'de ATS'lerde araç kullanıcılarının gizliliğini korumak için anonim kimlik doğrulama şemaları güven yönetim sistemleri kullanılarak oluşturulmuştur.…”

“…[13]'de ATS'lerde araç kullanıcılarının gizliliğini korumak için anonim kimlik doğrulama şemaları güven yönetim sistemleri kullanılarak oluşturulmuştur. Buna çok benzer olarak [14]'te, bir V2X sisteminde karşılanabilecek güvenlik ve gizlilik sorunları ve bunlar için geliştirilen çözüm önerileri tartışılmıştır. Ancak bu çalışmaların her ikisinde de yeni geliştirilen güvenlik ve gizlilik çözmelerine yer verilmemiştir.…”
