Hi,
I can't get my head around the cipher and auth used by SD132 in BLE (nrf52832,SDK12).
Could someone please explain which HW blocks and SW libs are used for encryption/decrytpion, authorisation and secure DFU? I know this is wide question, but I couldn't find any reference to AES CCM block in the SDK and I got confused, whether this is used by SD or not.
thanks
