A Trusted Execution Environment RISC-V System on Chip

This work proposes a new open-source hardware framework for Trusted Execution Environments (TEEs) on RISC-V systems. The framework is designed to be secure, flexible, and easily upgradable. It includes various cryptographic accelerators and an isolated microcontroller to improve boot performance. The design was implemented and tested on VLSI platforms to demonstrate its feasibility and effectiveness.
