Problems solved by technology
However, as the use of the Internet becomes more and more popular, many shortcomings are also exposed: 1) It is suitable for traditional one-time permanent authorization, and trial versions and on-demand purchases cannot be realized; 2) The existence of hardware brings additional production and initialization , logistics, installation and maintenance costs; 3) installation of drivers and client components and additional hardware devices affect customer experience; 4) electronic distribution based on the Internet cannot be realized; 5) it is difficult to perform upgrades, tracking and after-sales management
However, the current license file authorization mechanism still has obvious deficiencies in the use of institutional management environments, and it cannot realize modular authorization by user level
The organization administrator role cannot effectively manage the authorization information of ordinary users under it

Embodiment Construction
[0030] 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.
[0031] like figure 1 As shown, the embodiment of the present invention is based on the software authorization method of the public key cryptosystem, comprising the following steps:
[0032] S1. The server side receives the organization authorization certificate and the registration document from the client side;
[0033] The agency authorization certificate is encrypted and generated by the server according to the application information of the agency user, and is provided to the agency user for management and storage. The agency user distributes it to individual software users. Perform authoriza...

The invention discloses a software authorization method based on a public key cryptosystem, comprising the following steps: a server end receives an organization authorization certificate and a registration file transmitted from a client; the server end decrypts the received organization authorization certificate, and decrypts the decrypted After verification, if the verification is passed, the registration file will be encrypted, and the user authorization certificate will be generated and returned to the client; when the client starts the software, the software will decrypt and verify the user authorization certificate, and if the decryption verification is successful, start software, otherwise, the software does not start. The invention can prevent the software from being illegally copied, and at the same time, it is managed centrally by the software issuer, which is convenient for after-sales management such as upgrading and tracking of the software and pushing personalized services for users.
Description
technical field [0001] The invention relates to a software authorization method, in particular to a software authorization method based on a public key cryptosystem. Background technique [0002] The existence of piracy has become an important factor restricting the development of the computer software industry. Software is easy to copy and the copy cost is low. Now companies urgently need to take technical measures to protect their copyrights. Therefore, it is of great practical significance to study and design an effective, practical and secure software authorization method. [0003] In public key cryptography, the encryption key is different from the decryption key. Among all public key cryptosystems so far, the RSA algorithm is the most famous and widely used one. The RSA algorithm solves the problem of using the public channel transmission and distribution of the key of the symmetric encryption algorithm well. It can also use the RSA algorithm to complete the digital ...
