Nowadays, many industrial infrastructures are monitored and managed remotely through the network. These – typically SCADA (Supervisory Control and Data Acquisition) networks – are responsible for infrastructures that control systems ranging from the water supply to the electrical grid and are, thus, critical to our society. This use case intends to demonstrate the securing of this type of networks through QKD. Key Indicator: size and number of nodes protected, scalability of the solution.
