Real-time Mandatory Access Control on SELinux for Internet of Things

IoT devices such as an IoT smart home Server require the real-time processing and SELinux to ensure periodicity through fast response and protect private information using fine-grained access control. However, these two technologies have a conflict of interest regarding time management. SELinux has a latency due to the fine-grained access control, and the real-time process must reduce latency to ensure a periodicity. The alternative is real-time mandatory access control. Proposed Real-time Mandatory Access Control in this paper reduces the overhead of SELinux and secure the periodicity of the real-time process.
