Problems solved by technology

The existence of piracy not only caused huge losses to software developers, but also greatly hindered the development of the entire software industry
The input table, entry point function, and resource data of executable files, as important data of executable files analyzed by pirates, have always been the key objects of protection. At present, the pure software protection method for these data has poor anti-analysis performance, and it is easy to Be decompiled and analyzed, resulting in data leakage and destruction

Abstract

The invention discloses a method for protecting an executable file. The method for protecting the executable file comprises the steps of encrypting key data of an input list, an access point function, resource data and the like in a conventional file to be protected, then storing the key data to be stored into a file protection device, and eliminating the corresponding data in the conventional file; and taking the encrypted data out from the file protection device to be deciphered, and operating the deciphered data when the protected file operates. According to the technical scheme of the method for protecting the executable file, the difficulty of decompiling and analyzing the executable file can be enhanced, so that the security of software is greatly enhanced. The invention further discloses a system for protecting the executable file.

Description

technical field [0001] The application relates to the field of computer software protection, in particular to a method and system for protecting executable files. Background technique [0002] As a special product, computer software has been plagued by piracy since its inception due to its digital characteristics. The existence of piracy not only caused huge losses to software developers, but also greatly hindered the development of the entire software industry. The input table, entry point function, and resource data of executable files, as important data of executable files analyzed by pirates, have always been the key objects of protection. At present, the pure software protection method for these data has poor anti-analysis performance, and it is easy to It is decompiled and analyzed, resulting in data leakage and destruction. Contents of the invention [0003] In view of this, this application provides a protection device and method for executable files, which encry...
