Method and device for implementing management and control strategy of mobile terminal

Abstract

The embodiment of the invention provides an implementation method and a device of a mobile terminal management and control policy. The method comprises the following steps: under a trusted execution environment, calculating a digest of a first management and control policy currently obtained; if the digest is inconsistent with the first target digest, obtaining a second management and control policy stored in advance and set as read-only; In the trusted execution environment, according to the second control strategy, modifying the memory data corresponding to the control object. Since the second control strategy is implemented by modifying the real memory data corresponding to the control object in the trusted execution environment, the attacker in the ordinary environment can not directlyintervene and the control is invalidated, and the second control strategy is read-only, thus fundamentally ensuring the integrity of the second control strategy and not being tampered with. In addition, since the mobile terminal implements the management and control according to the second management and control strategy, the mobile terminal does not need to be locked, and the participation of the management and control platform is not required, thereby realizing the 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.
