TEE and trust: assessing the security of Arm’s TrustZone

Commercial TEE solutions using ARM’s TrustZone technology have been used for many years now. But are they enough on their own to guarantee security?

As the number of implementations increases and they become increasingly common in a large number of devices, it is worth assessing the continued security of these solutions.

This white paper focuses on the security and vulnerabilities of different TEE implementations using ARM’s TrustZone technology, highlighting how an attacker can gain access to Secure World assets.
