Abstract

The invention discloses a software program module integrity detection method based on a PKI public key algorithm, and the method comprises the steps: carrying out the signing of a program module through a fixed certificate based on the PKI public key algorithm and a dedicated loading module; verifying module signature, loading a module, decrypting an imported table envelope, restoring an importedtable and starting a signature verifying thread of a code region during operation through comprising a fixed public key certificate, modulate signature and imported table digital envelope; entering anoriginal program inlet point for continuing the execution, wherein the secret keys employed during signing are consistent with the certificates employed during signature verification in a one-to-onemanner. The beneficial effects of the invention lie in that the method protects software from being tampered and used illegally under the condition that the normal function of the software is not affected, and also protects the intellectual property of a software owner.

Description

technical field [0001] The invention relates to the technical field of software protection, in particular to a software program module integrity detection method based on a PKI public key algorithm. Background technique [0002] With the popularity of computers in daily production, various application software running on computers have become more and more abundant, and it can be described as a prosperous scene today. Behind the prosperity of various application software, driven by interests, various illegal tampering and cracking technologies for application software are also developing continuously. The main way is to modify the software through static or dynamic analysis methods, so as to obtain The use license of the software, the purpose of destroying the normal function of the software or executing malicious code. On the one hand, this kind of behavior makes the intellectual property rights of the software owner suffer, and on the other hand, it threatens the security...
