OP-TEE is a widely adopted Trusted Execution Environment (TEE) commonly used on ARM-based SoCs. While it is highly portable and often features strong vendor support, achieving a functionally working setup is only half the battle. There are surprisingly many pitfalls where a developer can successfully integrate OP-TEE, only to introduce subtle security misconfigurations that silently undermine the entire system's threat model.

In this talk, Richard will outline the hidden security traps and integration challenges he has encountered over the past few years on custom hardware. Attendees will learn which footguns to watch out for, ultimately saving them the countless hours Richard spent debugging these exact issues.
