Method for protecting computer software

Abstract

The invention discloses a method for protecting computer software and belongs to the technical field of information security. The technical proposal is that a first intelligent cipher key device is connected with a server computer; a second intelligent cipher key device is connected with a client computer; the client computer starts up the software installed inside the client computer; the software transmits an IP address obtaining request to the server computer; the server computer analyses the IP address obtaining request, obtains the IP address of the client computer, and transmits the IP address to the client computer after the IP address is encrypted by the first intelligent cipher key device; the client computer receives the encrypted IP address, judges whether the IP address is a legal IP address after the IP address is decrypted by the second intelligent cipher key device, if so, the second intelligent cipher key device is available, otherwise, the second intelligent cipher key device is unavailable. The invention improves the security of client software, and synchronously, the invention transfers the IP address after the IP address is encrypted so as to further improve software decryption difficulty.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a computer software protection method. Background technique [0002] 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 function of key generation, and can safely store the key, and can preset the function of encryption algorithm. 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, which can store the user's key or digital certificate. [0003] In today's increasingly developed information technology, more and more software that contains data information and involves p...

Problems solved by technology

[0003] 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 , bringing huge economic losses to software users or developers, and also making it impossible to continue further work

[0004] In practical applications, there have been instances where the 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 allow It runs on a specific computer or computers within a specific range. Therefore, if an illegal user obtains the software and the smart key device bound to the software through improper means, the confidential software can be used on other computers, giving software users and Confidential Information Brings Huge Loss
