OP-TEE open-source security for the mass-market
summary
OP-TEE is an open-source Trusted Execution Environment that Linaro upstreams and deploys in shipping products, keeping keys and sensitive code inside a small OS-like enclave while offloading routines as Trusted Applications. Work includes a large automated test suite, ports toward Cortex‑M/ARMv8‑M, and an IoT bootloader, but practical gaps remain: secure PIN input and secure display are partially implemented and not fully upstreamed. Goal is pragmatic risk reduction—make attacks expensive rather than promise perfect security.
