Embodiment Construction

[0019] As mobile terminals become more intelligent and their applications more abundant, more and more sensitive information involving business secrets or personal privacy is facing serious security threats. Various applications are constantly emerging on mobile terminals. If developers do not implement security reinforcement protection when developing these applications, hackers may take advantage of the inherent security holes in these applications to obtain the root authority of the mobile terminal operating system and easily intercept users' sensitive data. data. So far, how to ensure the security of the mobile terminal has become more and more important.

[0020] In order to provide a safe operating environment for mobile terminals, ARM has introduced TrustZone technology from the ARMv6 architecture. TrustZone technology divides the working state of the central processing unit into normal state and safe state. The environment running in the secure state is a trusted exe...

Abstract

The embodiment of the invention provides a trusted measurement method, device and system, electronic equipment and a storage medium, and the method comprises the steps: obtaining a switching instruction, and switching the operation environment of a mobile terminal into a trusted execution environment; obtaining an integrity state value of a memory state of the rich execution environment; measuringthe memory state of the rich execution environment to obtain a current value; and when the integrity state value is inconsistent with the current value, giving an alarm. According to the method, thetrusted execution environment is switched in, the memory state of the rich execution environment is measured in the trusted execution environment, and the effectiveness of measurement and the integrity and security of the memory are ensured, so that the system and data security of the mobile terminal are effectively ensured.

Description

technical field [0001] The present application relates to the field of mobile terminal security, in particular, to a method, device, system, electronic equipment and storage medium for trustworthiness measurement. Background technique [0002] As mobile terminals become more intelligent and their applications more abundant, more and more sensitive information involving business secrets or personal privacy is facing serious security threats. Various applications are constantly emerging on mobile terminals. If developers do not implement security reinforcement protection when developing these applications, hackers may take advantage of the inherent security holes in these applications to obtain the root authority of the mobile terminal operating system and easily intercept users' sensitive data. data. [0003] Therefore, the security guarantee of the mobile terminal becomes more and more important, and there is an urgent need for a method that can effectively protect the syst...
