Dear NXP community,
I am developing a custom board based on the imx6qsabresd board.
For security reasons, I'd like to hide some of the data (for example security key) placed in RAM.
Now, I am considering the following.
1. Scramble data on SDRAM
Scramble the target data in the RAM so that the value can not be read directly.
Is there such a function in SoC?
2. Processing on OCRAM
Hide some data and programs by running them on the internal RAM.
Is there a way to run the program on OCRAM?
I am using BPS based Linux (4.1.15).
Because Linux has memory management, I am considering implementing it with assembly code.
Any good ideas?
All suggestions are welcome.
Best regard,
Tasuku.
