Governments around the world are highly aware of the potential threats to national security from cyberattacks on critical national infrastructure. Whether it’s in the energy grids or transport networks, critical connected systems must be protected with military-grade security, and strong levels of resilience.
The three basic tenets of security – confidentiality, integrity and availability – are essential for any products and networks for smart energy, smart transport or any other management systems for critical national infrastructure.
Systems need to last for decades, which means devices need to be designed for scenarios where there may be complex and multiple ownership over the lifetime of the product while it is in use. Factors related to security might include ensuring sufficient memory for over-the-air updates to be delivered over the next 20 years or so; or storing keys in escrow so that if product support is no longer available in future, at least any new owners can still maintain security within the system and networks.
