Problems solved by technology

[0006] Although there are a large number of ready-made software shells on the market, these have been thoroughly researched and are easy to crack. There are even some one-key unpacking tools, such as unaspack, unpecompact, and caspr, etc.
At the same time, in the field of software protection, there is no use of national secrets in it at present. This method is the combination of the national secret SM4 algorithm and the national secret SM3 algorithm, which makes the software more secure and reliable, and promotes the use of the national secret algorithm in the field of software protection. use of

Abstract

The embodiment of the invention provides a protection method and device based on Windows platform software. The method comprises the steps of performing shell adding processing on a target program togenerate a program file after shell adding; in response to a password input instruction, performing anti-debugging judgment on the shelled program file, and if the current program is being debugged, exiting the program; otherwise, executing the target program by executing the shelled program file. In this way, cracking of the software target program code by a cracker can be effectively resisted, and the software core original code can be protected against cracking and leakage.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of software encryption, and more specifically, relate to a method and device for protecting software based on Windows platform. Background technique [0002] The copying of software products is quite easy, and illegal users copy and use software without permission, which seriously damages the economic interests of software development departments and software copyrights, and adversely affects the development of computer software. Therefore, it is particularly important to take certain preventive measures technically. [0003] Currently, software protection technologies mainly include software encryption and hardware encryption, such as software-based encryption shell protection and hardware-based encryption lock protection. Using hardware protection is a relatively safe technology, but due to the high cost, the current mainstream is to use software shells to protect software. There ar...
