RISC-V Summit 2022

This proposal introduces the Xuantie security system for Xuantie RISC-V based processors. It uses OPTEE as the security OS which is compatibility with Arm software system. It enhances the system security through security technology that is coupled with RISC-V architecture. The Xuantie security software stack follows Global Platform TEE security standard. Xuantie security system also eliminates the platform difference between Arm and RISC-V, developers can migrate trusted application from Arm to RISC-V easily.
