A Secure, Context-Aware Software Architecture for Real-Time IoT Applications

This paper introduces a novel, context-aware software architecture to enhance the security of real-time IoT applications. By integrating a robust Role-Based Access Control (RBAC) model that incorporates user location and time, we significantly strengthen protection against unauthorized access and potential attacks. This approach addresses the increasing demand for secure and reliable IoT systems, especially in critical infrastructure and sensitive applications. To validate the feasibility and performance of our architecture, we developed a functional prototype and conducted rigorous evaluations. The results demonstrate that the proposed architecture can effectively handle real-time constraints while ensuring high security.
