Secure Bootloader AES help

[marcobologna]

Hello!

I would like to use on kinetis KV11Z and MK22FX the bootloader with security aes. 
When I try to compile, it asks me for the file aes_security.h and I can't find it. 
Can anyone help me? 
Is there a step by step tutorial that helps to implement security aes in bootloader 2.5?
Thanks in advance.
Regards
Marco

Hi Macro,

aes_security.h and aes_security.c use MMCAU. This is a special hardware that KV11 and K22 haven't.You can only use software encryption and decryption. The code is in aes128_key_wrap_unwrap.c

Dear Jing

Thanks for your reply.

The aes128_key_wrap_unwrap.c is missing in the MCU-BOOT v 2.5  source code. How I can find it and how I can insert it? How use it?

Hi,

MCUboot has been integrated into SDK. You can find this file in SDK_2.6.0_TWR-K22F120M\middleware\mcu-boot\tools\tools\elftosb\common
