Local data entrance guard type safety management device and method for 5G mobile terminal

Abstract

The invention relates to a local data entrance guard type safety management device and method for a 5G mobile terminal. In the device, a safety module is connected to a communication link between an application processor and a communication processor in series; a storage device used for storing local data is connected through the safety module; the safety module is used for carrying out entrance guard type safety management on local data of the mobile terminal, determining whether an application program requesting to access the storage device is credible or not according to the credibility ofthe application program in the application processor, carrying out undifferentiated encryption on to-be-stored data generated by the credible application program and then storing the to-be-stored datainto storage device; or reading and decrypting the to-be-read data of the credible application from the storage device, and outputting the to-be-read data to the application processor; and the safetymodule is also used for encrypting data to be sent outwards in the application processor, compressing and encoding the data through the communication processor and sending the data to the air interface. According to the invention, full-disk encryption of local data flow trail is realized, and the risk of data leakage is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device and method for guarding security management of local data of 5G mobile terminals. Background technique [0002] To achieve secure storage of local data files, it is necessary to prevent the risk of local data information leakage caused by malware and operating system vulnerabilities that may exist in the mobile terminal. The traditional method of realizing local data storage of mobile terminals usually adopts specific software technical means, such as hook technology (API HOOK), etc., to change the data transmission process in the mobile terminal system, monitor and intercept the data before reaching the destination, and save the data. After processing, pass on. Hook technology supports operations such as creating, opening, modifying, copying and saving monitoring files. [0003] At present, the secure storage of local data in mobile terminals usually relies on ...

Problems solved by technology

At the same time, the operating system may be attacked by malware, and it is difficult to ensure the correct implementation of local data security storage. There is a risk that local data will be bypassed and not trusted and securely stored

The traditional guard-style encryption method inserts an encryption machine at the data entry and exit to realize data encryption and decryption. Due to the specificity of the device, this method has limited universal capabilities and can only support specific storage devices.
