Problems solved by technology

Although there are many software authorization and protection methods, such as registration code method, dongle method, inserting function restriction program, Key File protection, etc., the disadvantages of these methods are also obvious, or the algorithm is complex, the production cost is high, or it is easy to crack, the protection weak
[0003] With the popularization of the Internet, combined with Internet technology, someone proposed a method of software authorization and protection through online registration. Compared with other methods in the prior art, this method has high security and is not complicated in technical implementation, but this method The method only uses a unique connection between the application server and the database, and the database security is low

Abstract

The invention relates to a software authorization and protection device and method based on an asymmetric cryptographic algorithm. The device comprises a software seller client computer, a plurality of client computers, a software seller server, a database and a user server, wherein the software client computer is connected with the software seller server through wireless and / or wired networks, the software seller server is connected with the database through a first VPN (virtual private network), the user server is connected with the database through a second VPN, and a plurality of client computers are connected with the user sever through Internet. The invented device adopts double-backup connection between the application server and the database, and the database safety performance is improved. The invention also has another goal of providing the software authorization and protection method based on the asymmetric cryptographic algorithm. The method provided by the invention adopts an asymmetric cryptographic technology, the safety is high, the technology realization is not complicated, and the mode for obtaining the authorization by a user is simpler.

Description

technical field [0001] The invention relates to a software authorization and protection device and method based on an asymmetric encryption algorithm. Background technique [0002] Due to the reproducibility and repeatability of software, software developers and their development teams in the industry have always suffered from illegal software copying and pirated software products. Although there are many software authorization and protection methods, such as registration code method, dongle method, inserting function restriction program, Key File protection, etc., the disadvantages of these methods are also obvious, or the algorithm is complex, the production cost is high, or it is easy to crack, the protection Weak. [0003] With the popularization of the Internet, combined with Internet technology, someone proposed a method of software authorization and protection through online registration. Compared with other methods in the prior art, this method has high security and...
