Security in V2I Communications: A Systematic Literature Review

Area of Science:

• Cybersecurity
• Telecommunications Engineering
• Computer Networks

Background:

• The proliferation of wirelessly connected vehicles drives demand for advanced services like infotainment and autonomous driving.
• Vehicular networks, particularly vehicle-to-infrastructure (V2I) communication, offer significant advantages over vehicle-to-vehicle (V2V) due to roadside units' enhanced computational and transmission capabilities.

Approach:

• This paper systematically reviews principal vulnerabilities and challenges in V2I communications.
• It analyzes tools and methods for mitigating these vulnerabilities, including evaluation metrics and performance comparisons.
• The study identifies and assesses various security schemes, including attack-resistant designs, authentication, privacy models, and intrusion detection systems.

Key Points:

• Identified V2I vulnerabilities include susceptibility to attacks, insecure key management, and over-reliance on certification authorities.
• Evaluated security solutions commonly use computational cost and communication overhead as performance metrics.
• Emerging technologies like fog, edge, and cloud computing demonstrate superior performance in V2I security solutions.

Conclusions:

• The primary challenge in V2I communication is establishing and maintaining secure, reliable channels against adversaries.
• Security solutions leveraging fog/edge/cloud computing show the most promise for enhancing V2I communication security.
• Further research is needed to develop robust defenses against evolving cyber threats in vehicular networks.
