By reading the documentation on the DRAM encryption Memory Encryption — Jetson Linux Developer Guide documentation, my questions are the following:
- which key is adopted to encrypt/decrypt the data in RAM?
- should I set these parameters in bootloader/tegra234-mb1-bct-misc-common.dtsi right?
- how can I test and see that the data are encrypted in RAM? can you suggest some tools to check the encrypted ram?
