Problems solved by technology

However, for software in the .NET environment, since the compiled result of the .NET program is not a machine language code, but a kind of MSIL intermediate code, the traditional packing technology cannot be used, but a method in the .NET environment is required. The software packing method used

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 It is a schematic structural diagram of a software protection device based on shell technology provided by an embodiment of the present invention. Such as figure 1 As shown, the software protection device 100 includes a compilation module 110 , an encryption module 120 coupled to the compilation module 110 and an execution module 130 .

[0022] In an embodiment of the present invention, the compilation module 110 is used to compile the main program (that is, the program to be packed) into a dynamic link library (DLL) file, compile the shell program, and compile the shell program t...

Abstract

The invention provides a method for software protection based on a shell technology. The method is characterized by comprising the steps of compiling a main program into a dynamic link library file through a compiling module; writing a shell program through the compiling module; moving a running access of the main program into the shell program through an execution module, and compiling the shell program into an executable program through the compiling module; executing the shell program through the execution module, and dynamically loading and running the main program through the shell program. The method for software protection can prevent illegal copying of software, fingerprint authorization is performed for computer hardware, client access services of not a local server can be avoided for the network version, and high-strength software protection is achieved.

Description

technical field [0001] The invention relates to the technical field of computer software protection, and in particular to a software protection method and device based on shell technology. Background technique [0002] With the development of computer software technology, the infection and destruction ability of malicious software and the level of crackers have been greatly improved. For software with high security requirements, the protection effect of traditional soft encryption and hard encryption schemes is no longer obvious. Software encryption technology is gradually becoming mature, among which, shell encryption technology is a commonly used software protection method. [0003] The shell is an image metaphor for encrypted software, referring to a "coat" outside the software, which is a protective barrier for the software. Shell encryption technology refers to the use of a certain algorithm to encrypt and compress portable executable files, and add a shell to the file...
