Security Solutions for Networked Control Systems Based on DES Algorithm and Improved Grey Prediction Model
Compared with the conventional control systems, Networked Control Systems (NCSs) are more open to the external network. As a result, they are more vulnerable to attacks from disgruntled insiders or malicious cyber-terrorist organizations. Therefore, the security issues of NCSs have been receiving a lot of attention recently. In this paper, the authors review the existing literature on security issues of NCSs and propose some security solutions for the DC motor networked control system. The typical Data Encryption Standard (DES) algorithm is adopted to implement data encryption and decryption.
