Software license verification system and method based on digital signature

Abstract

The invention provides a software license verification system and method based on a digital signature, and relates to the technical field of digital signatures, and the system comprises a license management module which is used for generating an asymmetric key pair composed of a private key and a public key, obtaining application information, approving the application information based on the private key, and generating a software license after approval is passed; wherein the application information comprises an application code of the product, contract information and various restriction information of product use; the application code generation module and the license verification module are integrated in a product, the application code generation module is used for generating an application code, and the license verification module is used for obtaining a software license, a public key and application information, verifying the software license based on the public key, and verifying the application information based on current software and hardware information. The method can adapt to increasingly complex cloud service environments and effectively protect property rights of various software and hardware products in a software and offline implementation mode.

Description

technical field [0001] The invention relates to the technical field of digital signatures, in particular to a software license verification system and method based on digital signatures. Background technique [0002] In the process of gradual promotion of software and hardware products, software licenses need to be introduced to protect these types of products. The currently existing licensing methods are: [0003] 1. Online license application and online verification, but because a large number of software and hardware products need to work offline, this solution cannot meet the complex delivery and operating environment of each software and hardware product; [0004] 2. Hardware authorization, such as UKey, encrypted card, etc., but this solution cannot adapt to the increasingly complex cloud service environment. [0005] Therefore, improvements to current licensing schemes are needed. Contents of the invention [0006] The present invention provides a software licens...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a software license verification system and method based on digital signatures, which are used to solve the defects in the prior art that the authorization method does not support offline and must use hardware authorization, so as to adapt to the increasingly complex cloud service environment and use The way of software and offline implementation can effectively protect the property rights of various software and hardware products
