Policy Enforcement for IoT: Complexities and Emerging Solutions
Shuo Zhang, Luoyao Hao, Henning G. Schulzrinne · 2024
IoT devices benefit from nuanced policy enforcement to ensure safe, reliable, and efficient operations. However, the practical implementation of IoT policy enforcement systems involves multifaceted complexities. This paper delves into three-dimensional challenges: the intricacies of architecture and interoperational support, the expressiveness and safety concerns of policy languages, and the steep learning curve associated with policy creation. We investigate these areas, evaluate options, and prototype systems, considering the WoT, Pkl, and LLMs as potential solutions to address each challenge, respectively.
