Anti Rollback Protectiong for firmware loading

Hello,

I want to implement Anti Rollback Protectiong for firmware loading on S32K14x microcontroller so that only the latest signed firmware can be loaded rejecting the previous signed versions of firmwares.

#S32K14x

Regards,

Baseer

Hi @baseerahmadpiracha

The security module Cryptographic Services Engine(CSEc) of the S32K1 family is for encryption, decryption and authentication algorithms.

We are not seeing any Anti-Rollback Protection implementation.

So, all the implementation is up to you.
