Research On Android System Security And Design And Implementation Of The Monitoring Software

Under the premise to meet user needs, the openness of the Android mobile phoneplatform had a profound impact to the existing mobile phone operating system byproviding flexible development and service interactions. If there is no appropriatesecurity architecture and network prevention management, unknown or untrustedsources application unrestricted access to the phone sources as well as system API,will threaten the user privacy data.This paper first analyzes the current research trends of the Android platformsafety，Followed by a brief description of the overall system Android platformarchitecture, research Binder communication key technologies of the Linux kerneland Android API Android application development process used to package the classfiles. Then, propose a model of corresponding relationship between the requiredpermissions and in the source code of the Android application framework. The modelcould use as a checking mechanism of the privileges of Android applications, and thismethod can effectively prevent the abuse of the statement, false statement permissionshappened. Detailed design and implementation of the Android system monitoringsoftware according to the functionality and system monitoring software. The basicprinciple of the monitoring software is to read CPU, a list of file system, list ofprocessed，information of the local and remote IP address, port number, etc.Provided optimization algorithm of the privileges of the differences as well asmonitoring software in the paper, also provided a useful reference for further study ofthe safety of the Android system, and develop a similar application.
