Securing Miniaturized Ubiquitous Devices with Circuits Crossing Digital and Analog Domains

Security and privacy are critical challenges to ubiquitous electronics, such as loT and (body) sensor network. Securing these devices not only face new challenges at system and network levels due to drastically different applications, system constructions, and attack methods, but also face severe hardware-level constraints on computation resources, power consumption, and device cost. To solve these problems, new hardware security blocks are strongly demanded to provide a reliable, trustful, and energy-efficient foundation for building system security. In this talk, I will show our recent progress on novel hardware designs that cross the boundary between digital and analog electronics to provide fundamental security primitives and functions with ultra-low power and cost overhead. More specifically, experimentally validated mixed-signal security modules on true random number generators (TRNG) for key generation, physically unclonable functions (PUF) for chip fingerprinting and key storage, lightweight and reconfigurable cryptographic accelerators, and side-channel defenses will be highlighted in the talk.
