Embodiment Construction

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0030] A method for verifying the validity of the right to use software in this embodiment, such as figure 1 As shown, the specific steps are as follows:

[0031] Step A: Obtain the unique identifier of the device, and encrypt the unique identifier of the device to generate machine code ciphertext;

[0032] Such as figure 2 As shown, including the specific steps to generate the unique identifier of the device:

[0033] Step a1: Obtain the CPUID and network card address of the device;

[0034] Step a2: Concatenate the CPUID and network card address obtained in step a1 to obtain plaintext information;

[0035] Step a3: Generate the first public key A and the first private key A', and use the first public key A to encrypt the plaintext information to form ciphertext, which is the unique identifier...

Abstract

A method for verifying the legality of the software use right comprises the following steps: acquiring a unique identifier of equipment, and encrypting the unique identifier of the equipment to generate a machine code ciphertext; the authorization party decrypting the machine code ciphertext to obtain a unique identifier of the equipment, organizing authorization information of the decrypted unique identifier, and encrypting again to generate an activation code; the client decrypting the activation code to obtain authorization information, and writing the authorization information into a localmemory to form an authorization file; and when the software runs, the client recording the software running information, encrypting the software running information and storing the software running information in the authorization file in real time, and the authorization file decrypting the encrypted software running information and verifying the authorization information of the software. According to the method for verifying the legality of the software use right, the authorization information is obtained through multiple times of encryption and decryption, the authorization information is written into the local, the encrypted software operation information is stored into the local in real time, the authorization information is verified, and the purpose of controlling the software is achieved.

Description

technical field [0001] The invention relates to the technical field of software, in particular to a method for verifying the legality of the right to use software. Background technique [0002] In today's era of rapid development of the Internet and big data applications, software products have become the core tools in the computer field. In the world of dazzling software products, software protection ideas have gradually attracted the attention of software publishers. The full implementation of software protection is conducive to the development of the software industry. Healthy development is conducive to promoting informatization construction. The main reason for the illegal use of software is that the software authorization information between the licensor and the client is cracked, resulting in the illegal use of the software and causing heavy losses to the licensor. Contents of the invention [0003] The purpose of the present invention is to address the defects in ...
