Method and device for creating heterogeneous trusted execution environment and computing system

The invention discloses a heterogeneous trusted execution environment creation method and device and a computing system, relates to the technical field of computers, can cover a more comprehensive confidential computing scene, and has better applicability. The method is applied to the computing device comprising a first processor and a second processor which are heterogeneous, the first processor creates a first security isolation entity based on computing resources of the first processor, and the first processor sends a first creation request to the second processor; in response to the first creation request, the second processor creates a second security isolation entity based on computing resources of the second processor, and then the first processor performs integrity measurement on the second security isolation entity on the second processor side; and the second processor performs integrity measurement on the first security isolation entity on the first processor side. 一种异构可信执行环境的创建方法、装置及计算系统，涉及计算机技术领域，
