This article details GB 44495 test items, on-vehicle operations, testing depth, and enterprise cooperation requirements from a lab perspective.
·Full standard name: GB 44495-2024 Technical Requirements for Vehicle Cybersecurity
·Issued: August 23, 2024
·Enforced: July 1, 2026 (delayed from January 1, 2026)
·Scope: M-category (passenger vehicles), N-category (commercial vehicles), O-category vehicles with ECU and connectivity
2.Four Core Modules of GB 44495
·External Connection Security: Protection of external interfaces (wireless, physical, smartphone communication)
·Communication Security: In-vehicle bus (CAN, LIN, FlexRay) and Ethernet data protection
·Software Upgrade Security: OTA security mechanisms
·Data Security: Protection of personal data, location, and driving behavior
3.External Connection Security Test Items
T-BOX Wireless Communication Security
Mandatory test for connected vehicles: verify TLS/SSL encryption, valid certificates, identity authentication, and resistance to man-in-the-middle attacks.
Wi-Fi & Bluetooth
Test access authentication, secure pairing, and protocol vulnerabilities (all enabled functions are covered, even hidden ones).
Diagnostic Interface (OBD) Security
Verify access control (PIN code, role authentication), permission granularity, and diagnostic command restrictions.
USB & External Interfaces
Test resistance to malicious code injection, file access bypass, and power control; verify charging communication security for smart interfaces.
4.Communication Security Test Items
CAN Bus Message Authentication
Monitor and forge CAN messages to verify critical control message authentication and abnormal frame rejection.
Automotive Ethernet
Test VLAN isolation, access control lists, and switch security for domain-controlled vehicles.
FlexRay & LIN Bus
Verify basic message format verification and abnormal frame handling.
5.Software Upgrade (OTA) Security Test Items
Upgrade Package Integrity & Authenticity
Verify hash verification, digital signature, secure key storage, and HTTPS transmission.
Rollback Protection
Verify anti-rollback counters and rejection of downgrade attempts.
Interruption Recovery
Test power/network interruption recovery to prevent bricking.
Trusted Upgrade Source
Ensure only official upgrade packages are accepted.
6.Data Security Test Items
Personal Information Protection
Encrypted local storage, access control, log recording, and encrypted cloud transmission.
Location & Trajectory Data
Verify user consent, secure storage, and authorized access.
Security Logs
Verify log recording, tamper resistance, and storage management.
7.Often Overlooked Critical Items
·Secure Boot: Foundation of vehicle cybersecurity; incomplete boot chains invalidate all protections.
·Key & Certificate Management: Standard key generation, lifecycle management, and breach response.
·Security Status Monitoring: Anomaly detection for bus activity and network traffic.
8.Test Scope by Vehicle Configuration
·Basic models: T-BOX, OBD, CAN bus, basic OTA testing.
·Medium-complexity models: Added Ethernet, charging communication, and expanded data security testing.
·High-complexity models: Full test coverage with deep V2X, cross-domain security, and large-scale OTA testing.
9.Pre-Test Preparation Checklist
·Accurate network architecture diagrams.
·Security function descriptions consistent with real vehicles.
·Stable sample software versions matching mass production.
·Complete technical documents from key suppliers (T-BOX, OTA, security chips).
