FAQs

The main purpose is to guide automotive organizations in implementing secure V2X communication systems that comply with the ISO/SAE 21434 standard, ensuring the protection of data exchanges between vehicles and their environment against potential cybersecurity threats.

This checklist should be used by V2X system designers, automotive network engineers, cybersecurity specialists, embedded systems developers, and safety engineers involved in the development and implementation of V2X technologies in vehicles.

By ensuring the security and integrity of V2X communications, this checklist helps prevent unauthorized access, data manipulation, or disruption of critical safety messages, thereby enhancing the reliability of connected vehicle systems and supporting safer road environments.

The checklist covers various types of V2X communications, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N) communications, addressing the unique security challenges of each.

Key areas include secure communication protocols, message authentication and integrity, privacy protection mechanisms, certificate management, secure key storage, intrusion detection systems, secure over-the-air updates for V2X modules, and resilience against jamming and spoofing attacks.
