Apple Neural Engine Internal - From ML Algorithm to HW Registers

Delve into the inner workings of Apple's Neural Engine in this 30-minute Black Hat conference talk. Explore the reverse engineering of the Secure Enclave Processor (SEP) firmware, uncovering the FaceID software logic and neural network decryption parameters. Gain insights into why the SEP firmware decryption key for the iPhone XR has been leaked without compromising the FaceID machine learning model. Examine the connection between ML algorithms and hardware registers in Apple's neural processing unit.
