OP-TEE Trusted OS is the secure-world operating system implementation of the OP-TEE project, running on ARM TrustZone-enabled hardware. It implements a GlobalPlatform-compliant Trusted Execution Environment that isolates trusted applications from the normal (rich) OS.

Use cases

• run trusted applications isolated from the main OS
• implement a GlobalPlatform-compliant TEE on ARM hardware
• store cryptographic keys in a secure enclave
• build secure boot and DRM solutions with TrustZone
• develop secure-world firmware in C

When to choose

• you need hardware-isolated security on ARM TrustZone-capable SoCs
• you want an open-source GlobalPlatform TEE implementation
• you're building secure key storage, attestation, or DRM on embedded Linux devices

When to avoid

• your hardware lacks ARM TrustZone support
• you need a general-purpose OS rather than a secure-world environment
• you only need software-level encryption without hardware isolation
