In this project, Penn State University will expand the capabilities of a novel cybersecurity solution, TrustShadow, for Body Area Networks (BANs) consisting of multiple wearable devices and unmodified apps running on smartphones/tablets. Presently, only custom Operating System (OS) kernels and custom apps are compatible with TrustZone, limiting its applicability. Developed by AMD in 2004, TrustZone is a secure execution environment as an optional extension to hardware processers. Currently, extensive modification is needed to allow a usermode app to work with TrustZone. Enabling unmodified apps to operate within TrustZone through proposed technological innovations promises greater transparency, scalability, and practicality in addressing cybersecurity risks and safeguarding personal health data compared to conventional TrustZone implementations. This project aims to utilize the proposed TrustShadow technology to provide comprehensive protection for health data outside of clinical settings.
