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.

Abstract: In order to verify the authenticity of a product associated with a host device, the product contains, in segments of a non-volatile memory, several different functions stored in ciphered fashion. The host device sends a control signal for selecting and activating one of those ciphered functions. The product then deciphers and executes the function. The result of the function execution is then communicated back to host device when a decision on product authenticity is made.

Abstract: A first integrated circuit chip is assembled to a second integrated circuit chip with a back-to-back surface relationship. The back surfaces of the integrated circuit chips are attached to each other using one or more of an adhesive, solder or molecular bonding. The back surface of at least one the integrated circuit chips is processed to include at least one of a trench, a cavity or a saw cut.

The host device sends a control signal for selecting and activating one of those ciphered functions. The product then deciphers and executes the function. The result of the function execution is then enciphered and communicated back to host device when a decision on product authenticity is made.
