STAC-IoT: A secure task-based access control for IoT-edge computing architecture

This academic paper proposes STAC-IoT, a security framework designed to control who can access what in IoT-edge computing systems (networks of small internet-connected devices that process data locally rather than sending everything to a central server). The framework uses task-based access control, meaning it grants permissions based on specific jobs or functions rather than just user roles, to protect data and operations in these distributed systems.
