TIDM-TM4C123XSUB1GHZ: TM4C123x

Tool/software:

The TM4C123x supports AES and DES in ROM code. But what is the mechanism for secure key storage for these (or any other, user implemented) encryption standards?

Hi,

Note that this device does not support any asymmetric cryptography using public/private keys. The AES stored in the ROM is merely software code to implement the publicly defined encryption standard used by the U.S. Government. There is not really a secure key storage in this device.

OK, thanks for the clarification. So is there a way to do secure booting of this device? It seems that the answer would be 'No', but I just want to double check.

Hi,

No. Secure boot is not possible with this device.
