WebFor example, Intel SGX allows user-mode only, although Arm TrustZone and RISC-V Keystone run a trusted OS. In addition, each TEE has each SDK for programming. Each SDK offers own APIs and makes difficult to write a common program. These features make it difficult to compare the performance fairly between TEE and REE on different CPUs.
