MIIT published 50 communication industry standards including "Vehicle-Cloud Communication Security Technical Requirements for Vehicle-Road Cooperation" for public comment, with the comment period running from August 12 to September 10, 2026.
50 Standards Open for Comment Simultaneously
On August 11, 2026, the Ministry of Industry and Information Technology announced that according to the industry standard formulation and revision plan, relevant standardization technical organizations have completed the formulation of 50 communication industry standards including "Vehicle-Cloud Communication Security Technical Requirements for Vehicle-Road Cooperation." To further solicit opinions from all sectors of society, the standards are now published for public comment, with the comment period from August 12 to September 10, 2026.
These 50 standards cover multiple technical dimensions of vehicle-road cooperative communication. The most notable is the "Vehicle-Cloud Communication Security Technical Requirements for Vehicle-Road Cooperation" — this standard directly addresses the data security transmission specifications between the vehicle side and the cloud platform in the V2X (Vehicle-to-Everything) communication architecture.
Key Technical Points of Vehicle-Road Cooperative Communication
Vehicle-road cooperative (V2X) communication is the core infrastructure of intelligent connected vehicles. Its technical system includes the following key components:
- V2V (Vehicle-to-Vehicle): Real-time information exchange between vehicles for collision warning and platooning
- V2I (Vehicle-to-Infrastructure): Data exchange between vehicles and road infrastructure, supporting signal coordination and road condition sharing
- V2C (Vehicle-to-Cloud): Data upload from vehicles and command distribution from cloud platforms — the focus of this standard
- V2P (Vehicle-to-Pedestrian): Safety information interaction between vehicles and pedestrians or cyclists
The solicited "Vehicle-Cloud Communication Security Technical Requirements for Vehicle-Road Cooperation" focuses on solving the following security issues:
- Identity Authentication Mechanism: Ensuring the trusted identity of both vehicle-side and cloud-side communication parties
- Data Encryption Transmission: Preventing communication data from being eavesdropped or tampered with during transmission
- Security Protocol Framework: Establishing a unified vehicle-cloud secure communication protocol stack
- Anomaly Detection and Response: Real-time monitoring and handling of abnormal communication behavior
Standard System Accelerating
| Standard Category | Quantity | Focus Areas |
|---|---|---|
| Vehicle-Cloud Communication Security | Core standard | Data encryption, identity authentication, protocol security |
| Vehicle-Road Cooperative Communication | Multiple standards | V2X architecture, interface specifications, test methods |
| Intelligent Connected Vehicle Related | Supporting standards | Sensor fusion, high-definition maps, edge computing |
The establishment of vehicle-road cooperative communication standards has profound industrial significance:
- Unified Technical Foundation: Provides a technical basis for interoperability among V2X products from different automakers and equipment suppliers
- Reduced Deployment Costs: Standardized interfaces reduce customized development and accelerate large-scale deployment
- Enhanced Security Assurance: Strengthens the security defense line of intelligent connected vehicles from the communication level
- Export Compliance Basis: Provides technical standard endorsement for the export of Chinese intelligent connected vehicles and components
For Central Asian and Russian buyers following Chinese NEV and intelligent connected technology exports, the implementation of these standards means that the communication security capabilities of Chinese smart vehicles will reach new heights. The unification of V2X communication standards will enable Chinese exported intelligent connected vehicles to have stronger interconnection capabilities in overseas markets.

Industry Collaboration Trend
Notably, alongside the standard formulation, the China Association of Automobile Manufacturers Autonomous Driving Industry Development Joint Committee has also been launched. The joint committee will integrate the efforts of vehicle manufacturers, autonomous driving solution providers, chip and sensor enterprises, software and communication companies, and other parties, forming a positive interaction between standard formulation and industrial practice.
During the comment period, relevant enterprises and institutions can submit feedback through MIIT channels to participate in the co-construction of China's intelligent connected vehicle communication standard system.
