摘要： When an encryption processing circuit encrypts data, a current flows in the encryption processing circuit. A noise current generated by a noise generation circuit is superimposed on the current consumed by the encryption processing circuit. The present invention is applicable to an IC chip that encrypts plaintext data using a key, thus preventing the key from being broken by DPA attacks based on analysis of the current consumption to provide high security.

摘要： A semiconductor integrated-circuit device rectifies a received carrier wave, generates a first power-supply voltage based on the rectified output, and selects, as a power-supply voltage required for operation, one of the first power-supply voltage and a supplied second power-supply voltage. The first power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is lower than a threshold value. The second power-supply voltage is selected as the power-supply voltage required for operation when the second power-supply voltage is equal to or higher than the threshold value and an instruction to operate in accordance with a predetermined function is given.

摘要： When an IC card is passed over an external card reading and writing apparatus, the IC card starts communication with the card reading and writing apparatus via a wireless interface, so that a change in the internal state of the IC card is reported to an external device via an external wired interface or a dedicated control signal line, thus allowing a specific application to be enabled on the external device or allowing a controller to be powered on and activated. Alternatively, the controller is powered off and deactivated. Accordingly, processing according to the communication state between the IC card and the card reading and writing apparatus or the internal state of the IC card can be smoothly initiated.
