Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055] In one or more embodiments in this specification, the digital signature may sign each APK file. When the APK file is installed or running, the system will compare the digital signature to judge the integrity of the program, so as to determine whether the APK file can be installed, and achieve the purpose of security to a certain extent.

Abstract

The present application discloses a digital signature verification method, a medium, and a device. The digital signature verification method includes the following steps that: a first storage addressfor storing a digital signature to be verified, in an application installation file, is determined, wherein the digital signature is used for verifying the application installation file; the digital signature is read from the first storage address; and the digital signature is verified according to a message digest pre-stored in the application installation file. When the digital signature is verified, the method can avoid a defect that verification logic is decompiled, and a defect that the digital signature is tampered, and the reliability of the verification result of the application installation file can be improved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a digital signature verification method, medium and equipment. Background technique [0002] With the popularity of the Android platform, many excellent Android installation packages have been tampered with by criminals: either implanting malicious viruses; or adding advertisements, and then re-entering the channel through secondary packaging. [0003] For the anti-tampering of the installation package, the current market mainly uses the anti-tampering verification scheme, which is implemented through the Java language. Among them, the verification process is as follows: use Java language in the NDK (Native Development Kit, native development toolkit) layer, use Native methods / DLL / Lua scripts, etc. to obtain Java context / Activity objects, dynamic JNI reflection calls getPackageInfo, etc. To obtain the APK digital signature signature information, check whether the digital...
