Cybersecurity Beyond Software and Hardware | Christof Paar, Max Planck Institute

Описание: Abstract: Classical physical-layer security (PLS) has been studied for nearly half a century. In the past, the main objective had been to realize information-theoretically secure communication. Yet, those schemes haven't gained much practical relevance. We argue that it is more promising to apply PLS to problems for which there is no solution using digital-only schemes. In this talk we will look at a pretty wild application for such a PLS solution. A vexing problem in nuclear disarmament agreements is the secure remote monitoring of nuclear warheads in storage. In collaboration with Princeton's School of Public and International Affairs, we have developed an entirely new approach. Our solution is a special instance of a virtual-proof-of-reality scheme, based on radio-frequency signals. The basic idea is to build a challenge-and-response protocol -- which are widely used in cryptography, e.g., for authentication in mobile communication -- based on wireless technology.
