ARM Trust Zone

Last updated May 19, 2025, generated by Sumble

What is ARM Trust Zone?

ARM TrustZone is a system-wide hardware security extension for ARM processors. It divides the processor and memory into two virtual worlds: a 'secure world' for trusted operations and a 'normal world' for everything else. This separation allows sensitive operations, such as secure boot, DRM, and secure payment processing, to be isolated and protected from vulnerabilities in the normal world.

ARM Trust Zone Complementary Technologies

Trusted Execution Environment

Trusted Execution Environments (TEEs) provide a secure area within a main processor, often used with ARM TrustZone as a hardware foundation. They are strongly complementary as TrustZone provides the hardware isolation upon which many TEE implementations rely.

Secure Boot

Secure boot ensures that only trusted software can be loaded during the boot process. This complements ARM TrustZone by ensuring the initial state of the secure world is secure and hasn't been tampered with. TrustZone can be used to store the root of trust used in secure boot.
