Method for implementing protection of software based on network communication

Abstract

The present invention discloses a method for implementing protection of software based on network communication. The method comprises: a first key apparatus is connected to a server computer, and a second key apparatus is connected to a client computer; the client computer initiates software installed at an internal portion thereof; and the software detects whether the second key apparatus has been drawn out or not; if so, the software directly ends running; if not, the software sends an IP address acquisition request to the server computer, while an internal timing program of the software starts timing; and the server computer analyzes the IP address acquisition request to get an IP address of the client computer and transmit the IP address of the client computer to the first key apparatus; the first key apparatus encrypts the IP address and sends the IP address to the client computer. The method for implementing protection of software based on network communication disclosed by the present 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. USBKey is a smart key device with a USB interface. It has a built-in single-chip microcomputer or smart card chip ...

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
