Problems solved by technology

If APK1 is decompressed, modified and repackaged to obtain APK2, the same signature value as the original APK1 cannot be obtained, so the legal APK1 cannot be replaced

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] All features disclosed in this specification, except mutually exclusive features, can be combined in any way.

[0021] Any feature disclosed in this specification (including any appended claims and abstract), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0022] ZIP-based compressed files allow multiple identical paths to exist at the same time. In the Android system environment, if there are multiple files at the s...

Abstract

The invention provides an APK signature verification method in an Android system. The APK signature verification method in the Android system is based on APK signature verification methods in the prior art and comprises respectively putting a file needing execution and an original executable file into two folders; putting the two folders into the same folder compression package and meanwhile guaranteeing that the position of the file needing execution in the folder compression package is in front of executable files and that the position of the original executable file is at the back of the executable files. Therefore, not only is the signature verification is passed, but also new executable files can be executed. By means of the APK signature verification method in the Android system, monitoring can be performed on behavior of users of electronic products based on Android systems, such as cellphones, to prevent unsafe factors such as information leakage, or monitoring can be performed on illegal practices to meet requirements of security departments of public security bureaus and the like.

Description

technical field [0001] The invention relates to an APK signature authentication method, in particular to a method for APK signature authentication based on an Android system. Background technique [0002] Android is an open source mobile phone operating system based on Linux architecture developed by Google. The installation programs on it are all in APK (Android Package) format. APK is essentially a ZIP compressed file, which contains RES resource files, AndroidManifest.xml permission configuration files, and Classes.dex core dalvik virtual machine files. Both have been signed and authenticated (through the SHA1-RSA algorithm). [0003] When installing APK, the underlying core library file of the mobile phone will perform pre-install verification on the APK. The core method is to perform signature verification on Classes.dex and other resource files, and install them if they match. [0004] However, the only way for Android to distinguish installed APK packages is their p...
