How to encrypt NV stored DFU Images using nCS #EATON#

[Mohammed_Ubaid]

Hi,

I am looking for a sample programs for my use case, wherein :

1. I have to encrypt & store the DFU image which is present in secondary partition.

2. Decrypt the image and feed the same to bootloader mcuboot for its access.

Kindly help me with the sample programs.

Use case : the Secondary slot image should not be readable and should be encrypted

Hi Mohammed, 

Are you familiar with our DFU solution ? 
Have you implemented DFU feature in your application ? We use MCUBoot as the bootloader for the DFU update. 
MCUBoot support encrypting image however we don't support this feature natively in our nRFConnect SDK. 
One of my coworker has made a sample for it for nRF5340. Please take a look at this discussion: RE: Using MCUBoot with nRF5340 
The implementation for nRF54L should be quite similar. 

Let me know if you have follow up question.
