LPC55S69 : ICB-AES usage

Hello !

From hashcrypt SDk example it is quite clear how to use it in ECB and other modes.

But do you have ICB mode usage example what is explained in UM:

48.11.7 Using Indexed Code Book AES (ICB-AES) engine

?

Specially when key should be loaded from PUF ?

Regards,

Eugene

Hi, Eugene,

As you know that currently we have implemented ECB, CBC and CTR mode of AES algorithms in SDK package based on LPC55S6x, regarding the ICB-AES mode, I have searched in our internal data base, we have neither the code nor the further documentation for the mode.

I am sorry for not helping you.

Hi xiangjun.rong‌ !

Can you ask examples from headquarter . HW is validated somehow for sure and some examples should be available.

Block is public in UM and should be supported by SW somehow.

Regards,

Eugene

Hi, Eugene,

Unfortunately, we have not the plan to develop the code for the ICB-AES mode till now.

I've also tried setting up ICB-AES, but have run into various problems despite having normal AES ECB working fine.  Would be great to see some proof of concept by NXP!
