A way to perform frequent root-privilege operations and get real-time result feedback

Abstract

The invention discloses a method for frequently executing root privilege operations and acquiring real-time result feedbacks. The method comprises the following steps of: 1, implanting a root privilege escalation tool into a mobile phone; 2, analyzing reasons of memory consumption; 3, optimizing a process of the root privilege operations; 4, defining a data structure; 5, designing and realizing detection of privilege operation results; 6, designing and realizing execution of different operation requests in batch; and 7, clearing all calling resources and exiting. The method has the following beneficial effects: 1, the information in a specially established file list is allowed to be operated one by one with a root identity and the list may include multiple operations on files; 2, the occupation of a mobile phone memory can be controlled well while the root privilege operations are frequently carried out on the same file or different files, the reduction in the application efficiency and in the speed caused by excessive resource consumptions is avoided; and 3, whether the operations are successful is allowed to be verified and fed back after relevant root operations are completed.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for frequently performing operations with root authority and obtaining real-time result feedback. Background technique [0002] Root authority is the highest authority of the Linux system. The permission system of Android phones is consistent with that of Linux, but the Android systems released by various manufacturers usually only open permissions for ordinary users. If you need to obtain more data at the system level or belonging to other applications, you need to implant a privilege escalation tool in the mobile phone, and then obtain root privileges through certain operations. The tool runs on the bottom layer of the Android system (Linux layer), so the Android application needs to interact with the tool through a channel. The current common practice is: open the channel, perform ROOT-related operations, and close the channel. However, this prior art ...

AI Technical Summary

Problems solved by technology

[0004] 1. Unable to obtain real-time feedback information, that is, the result of permission operation

[0005] 2. Since the channel cannot be reused, when it is necessary to selectively operate on files one by one, it is necessary to frequently open and close the channel

This way of use consumes a lot of mobile phone hardware resources, which significantly reduces the smoothness and performance of application execution.

[0006] 3. For multiple root permission operations (for example, you want to delete a file, add a folder, and modify the permissions of a file at the same time), you can only build a shell for each operation and operate it, and the memory consumption is high.
