Embodiment Construction
[0049] Below in conjunction with accompanying drawing, the present invention is described in further detail; The present invention relates to following three links: (1) according to intelligent terminal equipment interaction characteristic, Android system framework design security GUI scheme; (3) Design a security display module based on the Android display system.
[0050] (1) Security GUI based on Xen virtual machine monitor;
[0051] Currently, the virtual isolation technology widely used in servers and desktops allows the creation of isolated containers to ensure system security. These containers, called virtual machines, provide better isolation than operating system processes.
[0052] The security GUI adopts virtual isolation technology to realize the isolation of the application and the system user graphical interface from the system architecture level, so as to ensure that the system graphical interface subsystem is not affected by the intrusion of malicious software...

The invention discloses a method for generating a safe GUI of an intelligent terminal based on virtual isolation technology. The method is as follows: 1) the virtual machine monitor divides the system into multiple isolated virtual machines, including a system virtual machine provided with a security flag module and application virtual machines with different security levels; 2) the package manager is divided into running The front-end package installer in the application virtual machine and the security level manager in the system virtual machine; 3) when an application is installed, the package manager sends the analysis information of the application to the security marking module to increase the security level information, expand it into security analysis information (sLevel, sSign); 4) the security level manager sends the installation instruction to the front-end package installer in the application virtual machine corresponding to the security level according to the sLevel value; 5) the system virtual machine Draw the interface of the application program on the GUI of the system virtual machine according to the sSign.
Description
[0001] Technical field: [0002] The invention belongs to the field of terminal security, and mainly relates to terminal system security, and more precisely relates to a method for generating a security GUI (graphical user interface) of an intelligent terminal system based on virtual isolation technology. Based on virtual isolation technology, this method adds a security launcher and in-app security prompts to the smart terminal system, expands the original user interaction system of the smart terminal, and provides a GUI security enhancement scheme for the smart terminal operating system. [0003] Background technique: [0004] The popularization of smart terminal devices and the increasing variety of smart terminal applications have greatly enriched the way people obtain information and brought great convenience to people's daily work and life. However, a wide variety of malicious software also brings great security risks to smart terminal devices. Attackers use malicious so...
