Abstract: A method includes configuring a memory for storing a kernel page table and a user page table to low-order address space, and reserving high-order address space, obtaining register configuration information of a kernel page table of a second operating system from the second operating system, and configuring a register of the high-order address space of a first operating system based on the register configuration information of the kernel page table of the second operating system such that the high-order address space is enabled to directly access a kernel resource of the second operating system.

Abstract: A system and method for authenticating network access of a terminal is described. The method may include sending, by the terminal, a user identity authentication request including first authentication information and second authentication information to an authentication server, where the first authentication information is used to authenticate a user identity of the terminal, and the second authentication information is used to determine a platform corresponding to the terminal. The method may also include after receiving user identity authentication acknowledgment information sent by the authentication server, sending, by the terminal to the authentication server, a platform identity authentication request including third authentication information used to determine the platform corresponding to the terminal. The authentication server sends platform identity authentication acknowledgment information to the terminal when determining that the platform corresponding to the second authentication information is consistent with the platform corresponding to the third authentication information.

Abstract: A Secure World access method includes creating a first virtual machine (VM) in a Normal World, loading a plurality of programs in the Normal World to the first VM, 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 VM running in the first-level mode, and stripping the first user program from the first VM, and loading the first user program to the second VM such that the first user program accesses the Secure World using the second VM.
