Brokering Policies and Execution Monitors for IoT Middleware
SACMAT(2018)
Abstract
Event-based systems lie at the heart of many cloud-based Internet-of-Things (IoT) platforms. This combination of the Broker architectural style and the Publisher-Subscriber design pattern provides a way for smart devices to communicate and coordinate with one another. The present design of these cloud-based IoT frameworks lacks measures to (i) protect devices against malicious cloud disconnections, (ii) impose information flow control among communicating parties, and (iii) enforce coordination protocols in the presence of compromised devices. In this work, we propose to extend the modular event-based system architecture of Fiege et al., to incorporate brokering policies and execution monitors, in order to address the three protection challenges mentioned above. We formalized the operational semantics of our protection scheme, explored how the scheme can be used to enforce BLP-style information flow control and RBAC-style protection domains, implemented the proposal in an open-source MQTT broker, and evaluated the performance impact of the protection mechanisms.
