How to provide authorization of app before connection?

[Newbie]

Hello, I am using secure_dfu_secure_dfu_ble_s132_pca10040 project. Now I want that the user who has specific key can only access the nrf my device and then can send the zip package for dfu. How should I implement this? I am using nrf52 amd sdk12. I am able to transfer zip package using nrf toolbox.

The file is nrf_ble_dfu.txt

Modified code is code.txt

Ble_gap.h ble_gap.txt

Dear Hung,

That was the best idea we came up with. If you have a better idea please let us know.'

We need to be able to do two things:

1. Once the product is out in the market we need the user's phone to be able to be the only phone that can authenticate the DFU and communicate with the product.

2. IF the user looses his phone we need the ability to factory reset the device and then have the new phone be the one to authenticate the DFU.

Please suggest.

Thanks
