Abstract:
A method for device authentication comprises receiving, by processing hardware of a first device, a message from a second device to authenticate the first device. The processing hardware retrieves a secret value from secure storage hardware operatively coupled to the processing hardware. The processing hardware derives a validator from the secret value using a path through a key tree. The first device then sends the validator to the second device.
