Blockchain technologies in the design of Industrial Control Systems for Smart Cities

Abstract: The proliferation of sensor technologies in Industrial Control Systems (ICS) helped to transform the environment towards better automation, process control and monitoring. However, sensor technologies expose the smart cities of the future to complex security challenges. Luckily, the sensing capabilities also create opportunities to capture various data types, which apart from operational use can add substantial value to developing mechanisms to protect ICS and critical infrastructure. We discuss Blockchain (BC), a disruptive technology with applications ranging from cryptocurrency to smart contracts and the value of integrating BC technologies into the design of ICS to support modern digital forensic readiness.
