Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the implementation manner.

[0051] The mobile terminal has a trusted execution environment and a common execution environment provided by hardware. In order to ensure the data security of the user's security applications, the security applications with higher data security requirements are run separately in the trusted execution environment, and the common execution environment is used. The application runs in a normal execution environment isolated from the trusted execution environment. However, since the current mobile terminal hardware can only provide a trusted execution environment for multiple virtual machines configured, all virtual machine users on the mobile terminal have to share the same trusted execution environment for runnin...

Abstract

The invention discloses a virtualization method of an execution environment, the method is applied to a mobile terminal, and the mobile terminal has a common execution environment provided by hardware; a common virtual machine and a trusted virtual machine are established for users in the common execution environment , the ordinary virtual machine is used to execute the user's ordinary application, and the trusted virtual machine is used to execute the user's security application; performing memory allocation for the ordinary virtual machine and the trusted virtual machine, and Establishing a mapping relationship between common memory and physical memory of the common virtual machine to obtain a first memory mapping table; establishing a mapping relationship between virtual physical memory and physical memory of the trusted virtual machine to obtain a second memory mapping table. The present invention utilizes two virtual machines to simulate a common execution environment and a trusted execution environment for users, so that common applications and safe applications run in independent execution environments, so that the execution environments of safe applications and common applications are isolated, and user data security is ensured.

Description

technical field [0001] The present invention relates to the field of virtualization technology, in particular to a virtualization of an execution environment, and a method and device for accessing the virtual execution environment. Background technique [0002] With the increasing popularity of mobile terminals, more and more data closely related to user privacy are stored in them, which also makes people pay more and more attention to the security of mobile terminals. An existing mainstream security solution is to use the trusted execution environment provided by the hardware to isolate the security applications running in the mobile terminal from the ordinary applications, that is, the security applications run in the trusted execution environment provided by the hardware of the mobile terminal, while the ordinary applications Then it runs in a common execution environment provided by the hardware of the mobile terminal. Hardware-level isolation can effectively ensure tha...
