Abstract
An integrated circuit includes a semiconductor-circuit layer; metal layers formed on the semiconductor-circuit layer, one of the metal layers being a metal layer in which an active shield is formed; and an antenna formed by patterning in at least one of the metal layers that are below the metal layer in which the active shield is formed. The semiconductor-circuit layer includes an encryption circuit configured to receive a drive voltage and to perform encryption arithmetic; a power-supply circuit configured to provide the drive voltage to the encryption circuit; and a circuit system configured to receive a power-supply voltage from an external power supply.
