Abstract:
A method of authenticating a slave device. The method includes initializing, by a host device, a charge retention circuit of the slave device, and receiving, by the host device, an indication of a discharge time of the charge retention circuit. The host device authenticates the slave device based on the received indication of the discharge time of the charge retention device.

Claim (Index 19):
A device, comprising:\n a charge-retention circuit having:\n a floating node; \n a first capacitor coupled between the floating node and a first reference-voltage terminal; \n a second capacitor coupled between the floating node and a second reference-voltage terminal; and \n a third capacitor coupled between the floating node and a third reference-voltage terminal, wherein the first, second and third capacitors have different charge retention capabilities; \n a communication interface to couple to a host device; and circuitry, which, in operation, responds to an initialization signal, by:\n initializing the charge-retention circuit, wherein the initializing signal switches off of a power supply associated with the charge-retention circuit; \n generating an indication of a discharge time of the charge-retention circuit; and \n controlling communication with the host device based on the determined indication.
