Abstract
A method and device for zero-trust fusion computation of multi-party data is provided, which adopts a chip-level based trusted execution environment (TEE) technique, and by improving a development preparation phase of a fusion computation background and improving a calculation phase, enable fusion computation of multi-party data to be performed in a zero-trust secure running environment, guaranteeing that the data is in a secure state without trusting any party during an entire process of transmission, storage and fusion computation, and allowing for enhanced data privacy protection. The solution brings many advantages in terms of data storage security, data transmission security and data use security as well as universality and performance superiority.
