Embodiment 1

[0064] In the present embodiment, the information security device can realize the c51 virtual machine function. Referring to FIG. 1, the present invention provides a method for .Net program protection, first perform the following steps:

[0065] Step 101: using a program protection tool to automatically separate a part of the compiled protected .Net program;

[0066] The separation refers to automatically searching and separating the qualified program segments according to the class or function name, and the separated program segments are part of the compiled .Net program (which contains the IL instruction text); conditional block;

[0067] Step 102: The program protection tool decompiles the separated program into a C# program, and can also be decompiled into other programs based on the .Net architecture, such as C++.net, J#, VB.net, etc.;

[0068] Step 103: the program protection tool converts the C# program into a high-level language C program using a syntax analyzer;

Embodiment 2

[0142] In this embodiment, the information security device can realize the x86 virtual machine function. Referring to FIG. 2, the present invention also provides a method for .Net program protection, first perform the following steps:

[0143] Step 201: using a program protection tool to automatically separate a part of the compiled protected .Net program;

[0144] The separation refers to automatically searching and separating the qualified program segments according to the class or function name, and the separated program segments are part of the compiled .Net program (which contains the IL instruction text); conditional block;

[0145] Step 202: The program protection tool decompiles the separated program into a C# program, and can also be decompiled into other programs based on the .Net architecture, such as C++.net, J#, VB.net, etc.;

[0146] Step 203: the program protection tool converts the C# program into a high-level language C program using a syntax analyzer;

Embodiment 3

[0159] In this embodiment, the information security device can realize the c51 virtual machine function. Referring to FIG. 3, the present invention also provides a method for .Net program protection, first perform the following steps:

[0160] Step 301: using a program protection tool to automatically separate a part of the compiled protected .Net program;

[0161] The separation refers to automatically searching and separating the qualified program segments according to the class or function name, and the separated program segments are part of the compiled .Net program (which contains the IL instruction text); conditional block;

[0162] Step 302: the program protection tool decompiles the separated program into an IL assembly instruction file;

[0163] Step 303: the program protection tool converts the IL assembly instruction file into a c51 assembly instruction file by using a syntax analyzer;

[0164] Step 304: the program protection tool uses the keil c51 compiler to co...

Abstract

The invention relates to a . net program protection method and system. It aims to solve the issue of hand modification, large volume of workload, complexity, and long development cycle, high cost, with the program protection tools dividing a part of the program to the coded . Net program, storing to the information safety equipment after conversion, writing the communication order to the separated . Net program for execution. It also provides a . Net program protection system which comprises automatic separation storage module and execution module. Due to the avoidance of hand modification progress, it greatly simplifies the development progress, improves development efficiency, and reduces development cost.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for protecting .Net programs. Background technique [0002] At present, with the development of computer technology, related technologies based on the Internet are getting more and more attention. Among them, Microsoft's .Net framework is a brand-new cross-language software development platform, which conforms to the major trends of today's software industry, such as distributed computing, component-oriented, enterprise-level applications, software as a service, and Web-centric. [0003] Information security equipment is a small hardware device with a processor and a memory, which can be connected to a computer through a computer's data communication interface, usually through a USB interface, and is usually called a USB KEY or USB Token. [0004] When using information security equipment to protect software, a part of the program can be written ...
