Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0054] The principle of the present invention is to place the kernel and the application of the rich execution environment in different virtual machines to run, and realize the transparent compatibility with the kernel and the application with the support of the virtual machine monitor and the user state library.

[0055] Concrete steps of the present invention include:

[0056] 1. When an ordinary application requests protection, the user state library ac...

Abstract

The invention relates to a method for protecting the interaction integrity and confidentiality of a trusted application and a common application. The method comprises the following steps: establishingmemory isolation between a kernel of a rich execution environment and an application by using a virtualization technology; by means of a virtual machine monitor and hardware virtualization support, operations of system calling, interruption and memory page swap-in and swap-out are transparently processed under the condition that a kernel and application codes are not modified; and establishing atrusted application and common application interaction library which is compatible with the original system and is not supported by the kernel drive. Compared with the prior art, the method has the advantages that multiple threads of hardware are supported, the kernel of the rich execution environment does not need to be modified, and more complete protection can be provided for common application.

Description

technical field [0001] The invention relates to the technical field of mobile platform security, in particular to a method for protecting the integrity and confidentiality of interactions between trusted applications and common applications. Background technique [0002] Trusted execution environment, especially the trusted execution environment based on TrustZone technology is gradually popularized on mobile terminals, and IntelSGX technology is gradually popularized on servers and desktop computers. Security issues that may exist on the rich execution environment side during common application interactions. [0003] The normal interaction process depends on the kernel software in the rich execution environment. A correctly implemented kernel can guarantee the security of the interaction and the isolation between multiple common applications. Therefore, the possible security problems in the rich execution environment are mainly due to the possibility of malicious kernels. ...
