Benefits of end-to-end IP for cyber and physical security

Security is a critical success criterion for implementation and operation of Smart Grids at any scale. In this paper I describe the status and specifics of Smart Grids where data communication and automation networks are integrated with the power grid. Increased connectivity in order to achieve higher flexibility, visibility and better control presents many benefits. On the other hand, increased connectivity comes with a couple of challenges, especially in security. Based on this situation, I introduce a concept of using the Internet Protocol (IP) as a foundation for end-to-end security as well as for the development of a framework for comprehensive security architecture in order to safeguard this critical infrastructure.
