On March 24, 2026, the 7th Standards Working Meeting of the Confidential Computing Special Interest Group (CC SIG) of the Global Computing Consortium (GCC) was successfully concluded. The meeting focused on core agenda items including the review of new standard proposals in the confidential computing field, the advancement of standards under development, and the compilation of the 2026 edition of the Confidential Computing White Paper. Following expert review and discussions, the meeting clarified the future direction and implementation plans for each initiative, injecting new momentum into the development of the standardization system and the implementation of technological achievements in China's confidential computing field, and promoting high-quality industrial development towards standardization and collaboration.

During the meeting, two new standard proposals became the focus of the review: "Security Technical Requirements and Evaluation Methods for Large Model Inference Based on Confidential Computing Clusters" and "Technical Requirements for Confidential Computing Environments Built on Trusted Platform Modules." Among them, the former aims to standardize eight major technical requirements, including hardware security of heterogeneous clusters, encrypted interconnect communication, node trusted access, and full lifecycle protection of model weights, providing technical specifications for confidential computing applications in large model inference scenarios. Experts specifically recommended that domestic computing power manufacturers and testing/certification bodies be invited to participate in the compilation phase, and that the formulation of technical requirements fully consider the technical capabilities and performance adequacy of domestic computing power to ensure the standard's practicality and industrial adaptability. Regarding the latter standard, participating experts pointed out that the focus needs to be adjusted towards IO isolation and AI acceleration-related specifications, and that this standard will also need to be revised and improved before being re-submitted for review.

Additionally, the meeting discussed interconnectivity specifications for heterogeneous TEE architectures. The need for this standard directly addresses the current challenges of secure and efficient interconnectivity among heterogeneous accelerators such as CPUs, GPUs, and DPUs, which arise from inconsistent technical paths and certificate formats. It aims to break down technical barriers by establishing unified specifications.

Regarding standards under development, the meeting received progress reports and updates on the handling of comments for two standards: "Technical Guidelines for Cryptographic Applications in Confidential Computing" and "Technical Requirements for Trusted Data Spaces Based on Confidential Computing." It was confirmed that both standards are progressing smoothly to the next stage.

The meeting also made special arrangements for the compilation of the "Confidential Computing White Paper (2026)." The white paper compilation team has been established and will strictly adhere to the timeline for content drafting, refinement, and improvement, ensuring that the white paper fully aligns with industry development realities and accurately captures technology trends, thereby providing professional references and directional guidance for technology R&D, industrial application, and ecosystem development in the confidential computing field.

Going forward, the GCC Confidential Computing SIG will take the lead in organizing relevant units to accelerate the revision and improvement of new standards, the solicitation of comments on standards under development, and the compilation of the white paper in accordance with the meeting's requirements. It will fully consolidate industry strength, strengthen collaborative innovation, continuously improve the standards system in the confidential computing field, promote the deep integration of technical specifications and industrial practice, and provide strong support for the innovative development of the global confidential computing industry.
