Method and device for implementing mobile terminal management and control strategy

Abstract

Embodiments of the present invention provide a method and device for implementing a management and control policy of a mobile terminal, the method including: calculating the digest of the currently acquired first management and control policy in a trusted execution environment, and if the digest is inconsistent with the first target digest, then Acquiring the second management and control strategy stored in advance and set as read-only; under the trusted execution environment, modifying the memory data corresponding to the management and control object according to the second management and control strategy. Since the second control strategy is implemented by modifying the memory implementation data corresponding to the control object in the trusted execution environment, attackers in the ordinary environment cannot directly intervene and cause control failure, and the second control strategy is read-only. Therefore, the integrity and non-tampering of the second management and control strategy are fundamentally guaranteed. In addition, because the mobile terminal implements management and control according to the second management and control strategy, there is no need to lock the mobile terminal, and the participation of the management and control platform is not required, thereby realizing safe and effective management and control of the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for implementing a management and control strategy of a mobile terminal. Background technique [0002] With the rapid development of the mobile Internet, sensitive businesses such as government affairs have a significant trend of mobile development. As the basic support of sensitive business, mobile terminals with high security level are of great significance to improve the work efficiency of industries with high security requirements and ensure the security of mobile Internet information. However, information leakage incidents of sensitive services caused by mobile terminals are not uncommon, and poor control of mobile terminal peripherals is one of the important reasons for such incidents. Therefore, how to ensure effective management and control of mobile terminals is one of the key issues for mobile terminals in the field of high security. [...

Problems solved by technology

[0004] Since the pre-stored management and control policies have been tampered with or deleted, it indicates that the general environment has been invaded, so that the new control policies received again may still be tampered with or deleted

Therefore, the current implementation method of mobile terminal management and control strategy cannot realize safe and effective management and control of mobile terminals when the management and control strategy is tampered with or destroyed.
