Description

This example demonstrates the soundness of the procedure used to stack/unstack the tasks' dedicated PAC key. The example is based on Corstone-315 Ecosystem Fixed Virtual Platform (Arm Cortex-M85 CPU and Ethos-U65 NPU).

The example consists of two main tasks (prvFirstTask and prvSecondTask). These tasks' job is to make sure that the task's randomly generated PAC keys are stacked/unstacked robustly without being altered.

Each application that is enabling the PAC feature shall
provide their own implementation of the random number
generator (RNG) to be used for generating random PAC
key for each task.
