Abstract: 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.

Abstract: To reduce power consumption for communication operation wherein a client terminal at the time of offline searches a base station or access point.A server uses a communication information predicting algorithm to predict a location or time whereby the server becomes an offline state over a movement route of a client terminal, and a location or time whereby the server returns to an online state, and informs to the client terminal. The client terminal suspends a communication function when reaching the informed offline predicted location or time. The client terminal at the time of offline determines that the current location or time has reached an online return predicted location or time using location recognition or point-in-time recognition, and restores the communication function.

Abstract: An RF (radio frequency) signal is generated at a first communication device and is modulated. A second RF signal provided to the first communication device from the second communication device is demodulated. The second RF signal is detected. The generating is actuated to initiate an active or a passive mode communication, when the detecting does not detect the second RF signal at a level of a first threshold or more, the active mode including a transmission of modulated data at the first communication device and the second communication device, the passive mode providing load modulated communication from the second communication device to the first communication device. When the first communication device receives an indication to start a communication of the active mode from the second communication device, the demodulating receives data at a level of a second threshold or higher, the second threshold being higher than the first threshold.
