The developments of ultra-low-power electronic devices brings opportunities for disruptive systems like the Internet of Things (IoT). The security and privacy issues of the huge amount of personal, sensitive, or safety-related data being processed in these systems are the main concerns. Ensuring security in these ULP systems face additional challenges than in computers because of power/cost constraints and physical accessibility by attackers. To solve these problems, innovations in both software and hardware are demanded.
This talk presents an overview of state-of-the-art hardware designs optimizing the trade-offs between security, power, and costs (including design and manufacturing costs) is presented. The connections between hardware specs and system demands are analyzed to bridge the gap between different research communities. Two methods for identifying and authenticating physical items will be presented, one is based on conventional cryptographic primitives and the other one is based on a new type of physical security primitive (physically unclonable function). Applying these security primitives to data security and privacy will also be discussed. The talk will be concluded with future research directions.
