汽车安全芯片应用领域白皮书_73页_6mb

Automotive information security involves risks to personal safety, data privacy, economic loss, brand reputation, and public safety due to intelligent vehicle connectivity. Challenges include lack of uniform standards, technological limitations, high costs, incomplete regulations, and insufficient user education. Key policy requirements include national laws like the Cybersecurity Law and Data Security Law, with standards such as GB 44495-2024. The significance of automotive chip security lies in protecting sensitive data and enabling secure operations for advanced features.

Communication security demands include encryption, identity verification, and secure protocols for V2X and other interactions. Other demands cover secure upgrades via OTA, access control for digital keys, and data integrity to safeguard user information. Security chips provide core functions like random number generation, encryption, key management, and attack resistance through features like PUF and countermeasures against side-channel attacks.

Application scenarios for security chips include T-Box for remote control and diagnostics, commercial T-Box for fleet management, gateways for data forwarding, intelligent cockpits for user interfaces, C-V2X for vehicle-to-everything communication, OTA upgrades, ETC for toll systems, and others like digital keys and battery authentication. Key technical requirements focus on capabilities like support for SM algorithms, high performance (low latency, low power), and reliability (AEC-Q100 compliance) to ensure secure operations. Certification includes CC EAL levels and functional safety standards, with trends toward stronger regulation, domestic chip adoption, and post-quantum cryptography.

To enhance security, policies should accelerate standard development, mandate secure chip use, and prepare for future quantum threats.
