Vanet Security and Privacy – an Overview
Keywords:
VANET Attacks; Security; Privacy PreservationAbstract
While vehicular ad-hoc networks (VANETs) offer substantial benefits to society, they also present numerous challenges, particularly in terms of security and privacy. Given the significant impact of VANETs on modern transportation systems, ensuring robust security and safeguarding user privacy are paramount. This paper provides an overview of VANET security and privacy, exploring fundamental challenges, state-of-the-art solutions, and emerging trends in this field. By examining the unique characteristics of VANETs, such as dynamic topology and resource constraints, this paper highlights the vulnerabilities inherent in these networks and the potential threats they face, including malicious attacks and privacy breaches. Additionally, the paper explores the intricate balance between security and privacy requirements, highlighting the trade-offs involved in deploying protective measures while preserving user anonymity and data confidentiality. Finally, the paper discusses future research directions and open challenges, advocating for interdisciplinary approaches and innovative solutions to address the evolving landscape of VANET security and privacy. This paper aims to provide researchers, practitioners, and policymakers with a nuanced understanding of the complex interplay between security, privacy, and attacks in VANET environments.
