IoTrust - a HW/SW Framework Supporting Security Core Baseline Features for IoT

The rapid growth of the Internet of Things has significant security implications. In the current IoT security landscape, many institutions and entities are defining security requirements, but no industry-wide standard has been agreed upon. There are solutions in the present state-of-the-art that fulfill a subset of secure IoT device requirements, but none adheres to all of them. However, the existing technologies introduced by those solutions could be combined to create a design framework which provides security baseline features to support requirements of a secure IoT device. In this paper, a configurable and comprehensive hardware-software security framework is proposed, that, when applied in the process of designing System on Chip for IoT, will ensure its cybersecurity by providing security core baseline features. The proposed sollution is CPU-agnostic, in the sense that no assumptions are made about the CPU's support for privilege levels, memory protection schemes, or any security mechanisms.
