TrustZone’s software model provides each world with its own copies of both lower privilege levels-- EL0 and EL1.This allows for the execution of different operating system kernels simultaneously - one running in the “Secure World” (S-EL1), while another runs in the “Normal World” (EL1).

Layered Security for Your Next SoC – Arm TrustZone Technology for Processor IP. Arm TrustZone technology is a system-on-chip (SoC) and CPU system-wide approach to security with hardware-enforced isolation to establish secure end points and a device root of trust. TrustZone for Cortex-A Processors; On The Performance of ARM TrustZone | DeepAI 06/24/19 - The TrustZone technology, available in the vast majority of recent ARM processors, allows the execution of code inside a so-called vTZ: Virtualizing ARM TrustZone - USENIX
