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 enciphered and communicated back to host device when a decision on product authenticity is made.
