An Approach to Secret Sharing Based Secure Remote Monitoring
Jie Sun, Ping Zhang, Bo Shen · IFAC-PapersOnLine · 2024
In this paper, a secure remote monitoring approach is developed based on secret sharing. In order to improve the confidentiality of the signals transmitted over the network, each sensor output signal and each control input signal are split into two shares and sent to two clouds. In each cloud, a partial residual signal is generated based on the received signals. Then the partial residual signals are fused to obtain the residual signal that contains the fault information. The proposed approach protects signals from being leaked, as only partial information is contained in each cloud. The proposed approach is illustrated with an example of the quadruple-tank.
