基于互联网的工业过程监控系统的安全性研究

对基于互联网的工业过程监控系统可能遭受袭击的各种情况进行分析,提出了三个方面的安全措施:为防止未授权用户恶意破坏控制系统,提出了对付网络袭击者恶意操作控制系统的安全保护措施;为防止未授权用户进入、操作控制系统,提出了身份认证保护策略;为保证控制数据传输的快速性和安全性,将高级数据加密标准AES与RSA相结合,实现了适合于实时监控系统的数据加密算法,并通过测量数据加密传输的网络时延来验证该算法的有效性。

Secure Internet-based Monitoring and Control for Industrial Processes

In order to prevent intruder from attacking Internet-based monitoring and control system for industrial processes,after analyzing the potential targets for malicious attacks,the main measures for protecting these targets are proposed:safety measure for stopping malicious attacks from the outside,user authentication and the encryption algorithm for real-time data.In order to ensure the real-time and secure transmission for control message,a new data encryption algorithm is proposed,which is the combination of AES and RSA.The end -to -end encryption latency of different algorithms is investigated to show the efficiency of the new algorithm for Internet-based real-time control applications.
