Beschreibung der Arbeit:

For the RISC-V architecture, there are several academic or commercial Trusted Execution Environment (TEE) solutions that have different requirements.
These solutions are based on RISC-V features such as processor modes, physical memory protection (PMP) and more. Especially regarding the processor modes, most RISC-V TEE frameworks require M-S-U modes to function correctly. Apart from the proprietary Hex-Five MultiZone [1], there are no solutions for embedded low-power RISC-V platforms that only implement M or M-U modes.
In this work we explore the challenges and chances of existing TEE frameworks and propose a new framework that can be deployed on embedded devices.
