In-Vehicle Communication Cyber Security: Challenges and Solutions.

Area of Science:

• Automotive Engineering
• Cybersecurity
• Network Communications

Background:

• In-vehicle communication is crucial for modern vehicles, supporting sensors and reducing wiring.
• Current cybersecurity solutions for vehicles are often protocol-specific and lack a holistic framework.
• Existing approaches fail to adequately address the growing cyber risks in connected vehicles.

Purpose of the Study:

• To critically review the literature on cybersecurity for in-vehicle communication systems.
• To present a comprehensive overview of in-vehicle network architecture, protocols, and security methodologies.
• To propose a novel, multi-layer secure framework for in-vehicle communication.

Main Methods:

• Literature review and critical analysis of existing cybersecurity solutions.
• Classification of in-vehicle communication protocols based on characteristics and usage.
• Development of a protocol and use-case-independent multi-layer security framework.

Main Results:

• Identified gaps in current cybersecurity approaches for in-vehicle networks.
• Reviewed machine learning, cryptography, and port-centric security techniques.
• Proposed a new multi-layer secure framework for enhanced in-vehicle communication security.

Conclusions:

• There is a significant need for dedicated, framework-based cybersecurity solutions for in-vehicle communication.
• The proposed multi-layer framework offers a promising, adaptable approach to mitigate in-vehicle cyber risks.
• Further research is recommended to address open challenges and explore future dimensions in automotive cybersecurity.
