Problems solved by technology
Most of the dual systems and multi-users provide isolation functions without real-time data encryption for application data
Although the sandbox technology can achieve real-time encryption and protection of application data, most of the encryption sandbox technologies currently on the market are sensitive to the application, that is, the original application needs to be modified, and the interface of the sandbox is called to perform the encryption. Encryption, to some extent, increases the difficulty for users

Embodiment Construction
[0036] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0037] A method for constructing a safe operating space for mobile terminals, such as figure 1 As shown, the application framework layer and the system library layer are simulated and modified in the original application layer so that the application is not aware and does not need to be modified. Such as figure 2 As shown, in order to achieve the above effects, a virtual framework module and a security class library module are provided in the sandbox. The virtual framework module adopts the idea of framework virtualization, and intercepts and replaces the classes and methods of the original application framework layer through dynamic proxy or Hook...

The invention provides a method for constructing a safe operation space of a mobile terminal, which comprises the following steps of: intercepting classes and methods of an original application framework layer by using a virtual application framework layer, and replacing a target application component in an interception result by using a standby component; Creating a security class library, and constructing an input / output interface, a JNI layer interface and a security package; establishing a class loading device, establishing a self-defined class loading device inheriting an original class loading device, loading a security class library through the self-defined class loading device; and when loading is completed, laoding a standby assembly through the self-defined class loading device.The invention relates to electronic equipment and a readable storage medium which are used for executing the method. According to the invention, the application framework layer and the system librarylayer are subjected to related simulation and modification in the application layer through the encryption sandbox technology, so that a sufficient encryption protection mechanism is provided for theapplication without modifying the original application, meanwhile, the use difficulty of a user is reduced, and the effects of no perception of the application, no modification and protected installation are achieved.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method for constructing a safe operating space of a mobile terminal, an electronic device, and a storage medium. Background technique [0002] With the development of the Internet and mobile Internet, mobile terminals have played an increasingly important role in life and work, and terminals equipped with Android operating systems are the most representative of them because of their openness and diversification. However, the quality of applications is uneven, and malicious programs take advantage of the gap, causing security risks to mobile terminals. Personal financial payment services and enterprise mobile management all have high requirements for mobile security. [0003] Files in the computer are stored in an encrypted manner, which is one of the means to prevent data leakage. Different encryption algorithms, the size of the key space and the location of the key stor...
