摘要
随着信息化与网络化深度融合及物联网的快速发展,工业控制系统中所存在的信息安全隐患日益突出。针对工控系统日益增多的恶意攻击,本文首先分析了其系统架构总体特点,研究了密码算法技术,提出了基于改进的白盒SM4算法;其次,基于国密算法,本文设计了控制系统加密安全方案,并针对可编程序控制系统设计了密钥管理流程;最后,按照南向通信与北向通信两部分,本文设计了控制系统通信网络安全方案。
With the deep integration of informatization and networking,along with the rapid development of the Internet of Things(IoT),information security risks in industrial control systems have become increasingly prominent.To address the growing number of malicious attacks on industrial control systems,this paper first analyzes the overall characteristics of the system architecture,studies cryptographic algorithm technologies,and proposes an encryption security solution for control systems based on an improved white-box SM4 algorithm and national cryptographic standards.Furthermore,a key management process is designed for programmable control systems,and a communication network security scheme for the control system is developed by dividing it into southbound and northbound communications.
