Problems solved by technology
In today's increasingly developed information technology, more and more software that contains data information and involves personal privacy and business secrets is running on the computer, and the software or the software itself running on the computer is easy to be illegally tampered with or illegally copied due to piracy , bring huge economic losses to software users or developers, and also make it impossible to continue further work
[0003] In practical applications, the existing software running in the computer is bound to the smart key device connected to the computer to improve the security of the software running in the computer. However, currently some software containing highly confidential information can only be used on a specific computer. If the illegal user obtains the software and the smart key device bound to the software by improper means, the confidential software can be used on other computers, causing huge losses to software users and confidential information

Embodiment
[0023] Embodiment: realize the method for computer software protection based on network communication, described method comprises the following steps:
[0024] Step A: The first smart key device is connected to the server computer, and the second smart key device is connected to the client computer;
[0025] Step B: The client computer starts the software installed inside it, and then, the software detects whether the second smart key device is pulled out, if pulled out, the software directly ends running; if not pulled out, then The software sends an IP address acquisition request to the server computer, and the timing program inside the software starts timing;
[0026] Step C: The server computer analyzes the request for obtaining an IP address, obtains the IP address of the client computer, and transmits it to the first smart key device, and the first smart key device encrypts the IP address and sent to said client computer;
[0027] Step D: The client computer receives t...

The invention discloses a method for realizing computer software protection based on network communication. A first intelligent key device is connected to a server computer, and a second intelligent key device is connected to a client computer; software, and then, the software detects whether the second smart key device is pulled out, and if it is pulled out, the software directly ends its operation; if it is not pulled out, the software sends a request to obtain an IP address to the server At the same time, the timing program inside the software starts timing; the server computer analyzes the request for obtaining an IP address, obtains the IP address of the client computer, and transmits it to the first smart key device, and the first The intelligent key device encrypts the IP address and sends it to the client computer; the invention greatly improves the security of the client software.
Description
technical field [0001] The invention relates to a method for protecting computer software, in particular to a method for realizing computer software protection based on network communication. Background technique [0002] A key is a parameter that is entered in an algorithm that converts plaintext to ciphertext or ciphertext to plaintext. Keys are divided into symmetric keys and asymmetric keys. The smart key device is a small hardware device with a processor and a memory, which can be connected to a computer through the computer's data communication interface. It has the functions of key generation, safe storage of keys, and preset encryption algorithm functions. The calculations related to the key of the smart key device are completely run inside the device, and the smart key device has the characteristics of anti-attack, and the security is extremely high. USB Key is a smart key device with a USB interface. It has a built-in single-chip microcomputer or smart card chip...
