mimxrt1052 System security

Hello everyone,

I am using the mimxrt1052dvl6b EVK, and I have developed the final code. So I just want to know how to implement security for my product, so no one can read the flashed firmware (readback protection). If somehow someone gets read access, how can I use cryptography to encrypt this firmware? Also, how can I prevent access through J-Link debug and stop any read/write operation? No one should be able to read or write the firmware, even if it is stored in external flash.

Please share any reference, reference manual, or steps to implement this.

Thank you.

Hi @raj20024, hope you are doing well.

Please check on the RT1050 HAB Encrypted Image Generation and Analysis community post, which contains information and a guide to use HAB encryption which may fit your requirements.

Let me know if the information is useful.
