Abstract(s)The pervasive use of embedded computing systems in modern societies altogether with the industry trend towards consolidating workloads, openness and interconnectedness, have raised security, safety, and real-time concerns. Virtualization has been used as an enabler for safety and security, but research works have proven that it must be extended and improved with hardware-based security foundations. ARM Trustzone has been used for the realization of Trusted Environments, however in this case real-time requirements are completely disregarded. This work in progress paper presents FreeTEE, an embedded architecture that emphasizes and preserves the real-time properties of the system but still guarantees security from the outset. TrustZone technology is exploited to implement the basic building blocks of a Trusted Execution Environment (TEE) as a lower-priority thread of a RTOS. Preliminary results demonstrated that the real-time properties of the RTOS remain practically intact.
