基于SM3算法的工业控制软件加密方法设计

Design and Implementation of Encryption Method for Industrial Control Software Based on SM3 Algorithm

随着工业的发展,工业控制系统的软件使用权问题日益受到关注。为了保护工业控制软件的使用权以及知识产权,本文设计了一种基于SM3算法的注册码生成与校验的方法。采用注册码授权的方式保护其知识产权,防止盗版软件传播。本文首先对SM3算法进行概述,随后分析工控机的特征并提出针对工业控制软件的加密方案。采用流程图、时序图的方式详细描述了整个流程,为工业控制系统软件安全问题提供一种有效的解决方案。

With the development of industry,the issue of software usage rights in industrial control systems is increasingly receiving attention.In order to protect the usage rights and intellectual property rights of industrial control software,this article designs a registration code generation and verification method based on the SM3 algorithm.Using registration code authorization to protect its intellectual property rights and prevent the spread of pirated software.This article first provides an overview of the SM3 algorithm,then analyzes the characteristics of industrial control computers and proposes an encryption scheme for industrial control software.The entire process was described in detail using flowcharts and sequence diagrams,providing an effective solution for software security issues in industrial control systems.
