Privacy has become an increasingly important issue. The RISC-V ecosystem has established multiple Task Groups to discuss and enhance security specifications related to RISC-V processors. Andes Technology actively participates in the IOPMP Task Group, driving the development and enhancement of the IOPMP specification to enable hardware isolation, thereby helping RISC-V establish a more secure Trusted Execution Environment (TEE). This presentation will explore RISC-V security features, introduce Andes Technology's security solutions, and further discuss how to build a trusted execution environment on RISC-V.
