The landscape of miniaturized wireless biomedical devices (MWBDs), including various injectables, ingestibles, implantables, and wearables, is rapidly expanding as proactive mobile healthcare proliferates. Such devices are constrained in physical size, power-consumption budget, storage capacity, and computing power. Yet, they handle sensitive, private information and require trust as they directly affect the health of the patient by means of stimulation and drug delivery.
ICAS LAB focuses on security as a fundamental component of these devices. Our research spans from a generic model for the lightweight implementation of data security through a domain-specific qualitative-quantitative threat-modeling and risk-analysis framework to actual hardware designs (subthreshold true random number generators, an anti-fuse one-time programmable memory, and obfuscation techniques).
