Secure DFU on sdk 11

[Sal]

Hi, I am trying to secure DFU on SDK 11 (NRF52). Would you please suggest if there is a way to secure firmware on old sdk, without upgrading to sdk 12+? Thanks.

I think you have 2 options:

1. Use the experimental bootloader_signing in SDK v10.

2. Port the Secure DFU in SDK v12 back to SDK v11.

I would prefer to go for option #2.
