Problems solved by technology

The second is that it completes context-sensitive and flow-sensitive static detection at the same time, while Wala and FlowDroid can only complete one of them
[0010] However, in practical applications, the analysis efficiency of existing technologies for Android applications is still very low. For example, most of the applications will have invalid methods. A lot of resources, and consume more time

Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] From the two aspects of code and actual analysis of use cases, it is found that FlowDroid has the problems of high memory usage and excessive time consumption when constructing CG and performing data flow calculations. Therefore, the present invention designs a data flow-based Android The application information leakage detection method is used to realize the application information leakage detection for the Android application to be tested, such as figure 1 As shown, the following steps A to F are actually performed.

[0046] Step A. Obtain the configuration file in the APK file of the Android application to be tested, and obtain the respective component information corresponding to each preset component type such as the Activity type component, the Service type component, the Content Provider type component, and...

Abstract

The invention relates to an Android application information leakage detection method based on data flow, which is based on an on-demand analysis algorithm, removes useless edges in a CG graph and updates the CG graph by identifying a third-party library and invalid method rules and combining with a CFG graph under the condition that the existing Apk code life cycle construction is not changed and the detection process is not greatly changed, finally, potential data leakage is found in the process of analyzing the data flow of the flow chart through FlowDroid, a lot of unnecessary operation can be reduced through the whole scheme design, it is obtained through test analysis that time occupation and space occupation during APK analysis can be effectively reduced through the design, and high performance is guaranteed while high precision is achieved.

Description

technical field [0001] The invention relates to a data flow-based Android application information leakage detection method, belonging to the technical field of information leakage detection. Background technique [0002] With the development of technology, people can obtain rich resources and perfect services on the Internet through mobile devices, and more and more users access the Internet through mobile phones. According to the analysis of the 46th "Statistical Report on China's Internet Development" released by China Internet Network Information Center, as of June 2020, the number of Internet broadband access ports reached 931 million, and the number of Internet users reached 940 million. Among them, the number of mobile Internet users It has reached 932 million, accounting for 99.2% of all Internet users. [0003] The huge number of mobile smart devices has greatly changed people's lives, and in the current smart phone market, Android occupies the largest proportion. ...
