METHOD, APPARATUS AND SYSTEMS FOR ACCESSING SECURE WORLD

摘要

This application provides a Secure World access method, apparatus, and system, to improve security of a Secure World. The method includes: creating a first virtual machine in a Normal World; loading a plurality of programs in the Normal World to the first virtual machine, where the plurality of programs include a kernel and at least one user program, the kernel runs in a first-level mode, the at least one user program runs in a second-level mode, and the first level is higher than the second level; when it is determined that a first user program in the at least one user program needs to access a Secure World, creating, in the Normal World, a second virtual machine running in the first-level mode; and stripping the first user program from the first virtual machine, and loading the first user program to the second virtual machine, so that the first user program accesses the Secure World by using the second virtual machine.
