Abstract
The present disclosure provides an execution environment virtualization method. The method includes: creating an ordinary virtual machine and a trusted virtual machine for a user in the ordinary execution environment, where the ordinary virtual machine executes an ordinary application of the user, and the trusted virtual machine executes a security application of the user; allocating memories to the ordinary virtual machine and the trusted virtual machine; establishing a mapping relationship between an ordinary memory of the ordinary virtual machine and a physical memory, to obtain a first memory mapping table; and establishing a mapping relationship between a virtual physical memory of the trusted virtual machine and a physical memory, to obtain a second memory mapping table. Therefore, the ordinary application and the security application run in execution environments independent of each other, thereby ensuring data security of the user.
