Trusted Environment-based Cryptographic Computing (TECC): White Paper Overview and Technical Architecture

On September 26, the industry’s first "Trusted Environment-based Cryptographic Computing (TECC) White Paper" was published, offering an in‑depth analysis of data circulation trends, the TECC technical system, application scenarios, and future development directions.

01 Data Secrecy Era – Three Stages and Technical Requirements The paper defines three progressive stages: "Computation Secrecy", "Big Data Secrecy", and "Data Element Secrecy", each with distinct technical demands such as high performance, reliability (99.99% uptime), low cost, broad applicability, and strong security.

02 TECC Technical System TECC combines trusted execution environments with cryptographic protocols to enable secure, high‑performance, multi‑party data processing. Core features include in‑trusted‑node secret computation, decoupling of data owners from compute parties, and controllable out‑of‑domain secret encapsulation. Enhanced capabilities involve safe programming languages, formal verification, multi‑level trusted nodes, and tolerance to partial node compromise.

03 TECC Applications and Technical Evolution TECC has been deployed within Ant Group for financial‑grade security, supporting privacy set‑intersection, privacy‑preserving machine learning, and secret data analytics. It can process billions of records per hour, handle arbitrary numbers of participants, and integrate with large‑scale data centers such as the East‑West data computing initiative.

The architecture consists of participant layer, scheduling layer, distributed computing layer, runtime environment layer, data layer, and hardware layer, each contributing to secure data flow, isolation, and high‑throughput processing.

Key advantages highlighted are resistance to real‑world attacks, near‑plaintext performance, support for unlimited participants, competitive cost control, and enforced separation of data ownership and usage rights through secret data capsules.

The white paper concludes that TECC’s future evolution will require redesign of cryptographic algorithms and enhancements to trusted execution environments (TEE) to meet the demands of massive secret computation, including high‑performance CPUs, fast I/O, large memory, and GPU acceleration.

Overall, TECC represents a novel integration of cryptographic protocols, trusted computing, and full‑stack security, providing a foundational capability for the emerging data secrecy era.
