TrustZone context management API defines a set of secure function calls from NS RTOS handler mode to TF-M Core to get notification of context switch. TrustZone protected“services”through some kind of service manager. The mentioned API specification does not cover most aspects of the backend“service provider API”interface of the service manager. At the time of writing, the author is not aware of any publically available open implementation of the API described in [5]. Consequently the ARM spec- TrustZone also expands the standard “Exception Level” privilege model for the CPU. Before TrustZone, three levels existed: EL0 (user-mode), EL1 (kernel-mode) and EL2 (hypervisor-mode). TrustZone adds a new EL3 (secure monitor mode), which is the most privileged level and controls the entire system.
