Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] figure 1 The implementation flow of a software package certificate protection method provided by the embodiment of the present invention is shown, and the details are as follows:

[0020] Step 101, verifying the self-signed software package to obtain a verification value.

[0021] Specifically, when the developer self-signs the software package, he records the current time, which is the self-signature time, generates a signature value, and adds the signature value and the corresponding self-signature time to the self-signature file. The above software package includes the main program, plu...

Abstract

The invention is applicable to the technical field of software, and provides a software package certificate protection method and device. The method includes checking a self-signed software package to acquire a check value and self-signing time which is recorded when the software package is self-signed, matching the check value with a signature value which is recorded when software is self-signed, acquiring current time if the check value and the signature value are equal, rejecting installation otherwise, and determining whether to allow installing the software package or not according to the self-signing time and the current time. Therefore, service life of the self-signed software package is limited, market circulation capability of the self-signed software package is controlled, and application of pirated software is prevented.

Description

technical field [0001] The invention belongs to the technical field of software, and in particular relates to a software package certificate protection method and device. Background technique [0002] In the current popular Android system, software packages are divided into self-signed software packages and release-certified software packages. Self-signed software packages are untrustworthy and are only used for developer testing and release. However, self-signed software packages can be installed on the terminal, and self-signed software packages cannot be verified, resulting in pirated applications through self-signed software. , harming the rights and interests of developers and users. Contents of the invention [0003] The purpose of the present invention is to provide a software package certificate protection method and device that determines whether to allow installation according to the self-signed time and the current time, aiming at the problem of rampant pirated...
