Abstract
A client application in a rich execution environment sends a registration instruction of a secure memory to a trusted application in a trusted execution environment, where the registration instruction carries a memory address. Based on the registration instruction, a trusted application calls a registration interface of an operating system in a trusted execution environment, and sends a registration request of the secure memory to a processor trusted framework unit, so that the processor trusted framework unit updates, based on the registration request, an attribute of memory space corresponding to the memory address to a secure attribute.
