Abstract: Distributed devices are rarely initially designed with security in mind. The post-hoc addition of security features in an embedded system comes at a substantial cost. This incremental cost is largely a function of the real-time or near-real-time deadlines that device needs to adhere to and the additional computational burden of cryptographic algorithms. This cost can articulate itself in additional energy requirements, a concern for IoT devices, or increased computational power a concern for cost efficient automation components and IoT devices. In this presentation we examine, based on real-world measurements, the costs that can be expected using secure elements, HW-protocol implementations and co-designed systems. We begin by outlining the major design methodologies and their effect on the implementation and the choice of components for secure devices. We shall then discuss computational cost, security of implementation, footprint and other issues like testability and maintainability to leave the listener with a series of implementation options and key points to watch. We provide measurement results to support our arguments.
