Problems solved by technology

[0004] (2) The method of binding computer hardware (hard disk or network card) or operating system configuration information, the problem is that when the hardware or operating system changes, the software needs to be re-bound, and can be replaced by replacing the hardware Where the software is installed
[0007] To sum up, there are some defects in the existing methods, especially in the face of decompilation and memory copy technology, theoretically speaking, the software protected by the above methods can be cracked

Abstract

This invention has publicized a method basing on the safe CMOS chip to protect software. The following steps are included: firstly, the cell needing to be protected will be confirmed from software at least, each of which contains several cells. Secondly, the cell above will be translated and edited into the aim files executable by the safe CMOS chip. Thirdly, the aim file will be encrypted by the symmetrical key corresponding to the every software to produce the cryptograph cell. And then a function to transfer the safe CMOS chip will be set aim at the above files, and the cryptograph cell will be taken as the parameter of the function. The cells needing to be protected in software will be displaced by the function, and the cryptograph cell will be added to corresponding software. We can used this installation to avoid the software be deciphered and used illegally, and it is effective to the deciphered technology for the counter-translation and memory copy.

Description

technical field [0001] The present invention relates to the technical field of information security and trusted computing, in particular, the present invention relates to a software protection method capable of preventing cracking and a corresponding protection system. Background technique [0002] Software protection technology has always been a hot spot in the field of information security research. In today's Internet age, once the software is cracked or illegally copied in some way, it will bring huge losses to the software copyright owner. Therefore, various protection methods have been developed, among which the more common software protection methods are as follows: [0003] (1) A method of inputting a password or key during software installation, wherein if an incorrect password is entered, the installation process is terminated or only limited functions can be used. However, once the password is stolen or disclosed by the owner, the software can be installed at wi...
