As part of the CS 598 IoT Security and Privacy course at the University of Illinois Urbana-Champaign, our team — Abdulrahman AlRabah, Ben Civjan, Shalni Sundram, and Sam Yuan — developed a system that introduces role-based access control to the Matter smart home protocol. The project addressed the lack of fine-grained permissions and consistent logging within smart home environments by extending Matter’s Home Assistant integration.

Our implementation enriched Matter’s device logs with structured metadata, enabling controlled visibility based on user roles and permissions, and provided a web interface for managing user groups and viewing filtered logs directly within Home Assistant. The project was tested in collaboration with Dartmouth’s IoT research lab, where it successfully demonstrated secure and scalable access to Matter device data.

This work was later presented at the SDIoTSec’24 Workshop, where it won the Distinguished Paper Award for its research contribution and implementation quality.
