Secure Bootloader AES help

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,

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

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?
