On 11 August 2025, the National Technical Committee on Data Standardization (SAC/TC609) opened a public consultation on 3 technical documents on data infrastructure and 3 technical documents on trusted data space. These 6 technical documents are developed to support the Guidelines for Construction of National Data Infrastructure (released on 1 Jan 2025) and the Action Plan on Developing Trusted Data Space (2024–2028), and to facilitate the planning, construction, operation, and management of data infrastructure and trusted data spaces across regions, industries, sectors, and enterprises.
The 6 technical documents and their scopes are presented below:
- TC609-6-2025-XX Data infrastructure – Technical requirements for Regional/Sectoral Functional Nodes
This document specifies the interrelationships, functional architecture, and technical requirements for regional/industry functional nodes in areas such as product and resource management, identification management, operations management, and monitoring & analysis. It is applicable to guiding qualified provincial authorities, industry regulators, and leading enterprises in constructing regional/industry functional nodes based on standardized architecture.
Furthermore, this document supports the development of multi-tiered data infrastructure—including regional, municipal, industrial, corporate, and individual-level systems—supported by technological frameworks such as data markets, trusted data spaces, the Internet of Data, data components, privacy-preserving computation, and blockchain.
- TC609-6-2025-XX Data infrastructure – Access management
This document specifies the technical, managerial, security, and compliance requirements for integrating business nodes and access connectors into regional/industry functional nodes during the construction of data infrastructure.
It is applicable to guide the access management practices of regional/industry functional nodes, as well as supporting the integration of business nodes and access connectors into the data infrastructure ecosystem.
- TC609-6-2025-XX Data infrastructure – General requirements for security capability
This document specifies general security capability requirements for data infrastructure. Based on the functional architecture of data infrastructure and incorporating the security assurance layer, it outlines security capability requirements for components within the data circulation and utilization layer, computing power layer, and network facility layer.
This document is applicable to all stages of data infrastructure, including planning, construction, operation, and evaluation. It aims to provide comprehensive security guidance to stakeholders involved in data infrastructure, ensuring confidentiality, integrity, availability, and overall security of data.
- TC609-6-2025-XX Trustworthy data space – Technical requirements for digital contract
This document specifies the structural, content-related, technical, and security requirements for digital contracts, and describes their business processes, interfaces, and data dictionaries.
It is applicable to the design and development of digital contracts, and provides technical guidance for the construction, operation, and evaluation of related systems.
- TC609-6-2025-XX Trustworthy data space – Technical requirements for usage control
This document specifies the technical requirements for usage control in trusted data spaces, including functional requirements, interface specifications, and security requirements. It applies to the design and development of data usage control functions within trusted data spaces, and serves as a reference for the construction, operation, and evaluation of data usage control modules in trusted data space service platforms and connected connector.
- TC609-6-2025-XX Trustworthy data space – Specification for technical capability evaluation
This document specifies requirements for capability evaluation of trusted data space technology and applies to technical selection and third-party evaluation for trusted data space.
SESEC will continue to monitor the development progress of these 6 technical documents and provide timely updates once their final versions are officially released.
