Embodiment 1

[0023] An application soft isolation method based on a security domain-based smart phone operating system. The method can effectively prevent the above-mentioned various loopholes by coloring applications with different security levels and strictly controlling inter-process communication, and realize application security. Software isolation ensures the security of private data in applications.

Embodiment 2

[0025] Such as figure 1 As shown, on the basis of Embodiment 1, the method described in this embodiment realizes software isolation by using process coloring, and process coloring is realized by four modules, which are respectively an application color configuration module, a process coloring module, an application color database, and a process coloring module. Inter-communication management module, in which:

[0026] The application color configuration module is responsible for color storage and configuration of applications with different security levels;

[0027] The process coloring module is responsible for coloring the processes of a specific application.

Embodiment 3

[0029] On the basis of Embodiment 2, the application color configuration module described in this embodiment is composed of two Activity components: BrowseAppActivity and SettingColorActivity, wherein BrowseAppActivity mainly displays all currently installed applications; after the user clicks on the corresponding APP displayed here, Enter SettingColorActivity, the user selects a color for the APP on this page, and stores the set color data in the application color database.

Abstract

The invention discloses a method for application soft isolation of a smart phone operation system based on a safety margin. The method is characterized in that applications with different safety grades are toned; inter-process communication is controlled; and software isolation of application programs is achieved. According to the invention, safety margin technologies are used for application isolation of a smart phone; the method can be applied to intelligent terminal products; through coloring of the applications with the different safety grades and strict control of the inter-process communication, various abovementioned loopholes could be prevented effectively; the software isolation of the application programs could be achieved; and safety of private data in the application programs could be guaranteed.

Description

technical field [0001] The invention relates to the technical field of security domain isolation, in particular to an application soft isolation method of a smart phone operating system based on a security domain. Background technique [0002] Definition 1: A security domain is a logical area composed of a group of systems that have the same security protection requirements and trust each other. [0003] Definition 2: A security domain is a collection of IT elements that are in the same working environment, have the same or similar security protection requirements and protection strategies, trust each other, are interrelated or interact with each other. [0004] Definition 3: A security domain refers to a network or system within the same environment that has the same security protection requirements, mutual trust, and the same security access control and boundary control policies. [0005] At present, the more popular methods of dividing security domains are: dividing acco...
