摘要： There is a need for providing a battery-less integrated circuit (IC) card capable of operating in accordance with a contact usage or a non-contact usage, preventing coprocessor throughput from degrading despite a decreased clock frequency for reduced power consumption under non-contact usage, and ensuring high-speed processing under non-contact usage. A dual interface card is a battery-less IC card capable of operating in accordance with a contact usage or a non-contact usage. The dual interface card operates at a high clock under contact usage and at a low clock under non-contact usage. A targeted operation comprises a plurality of different basic operations. The dual interface card comprises a basic arithmetic circuit group. Under the contact usage, the basic arithmetic circuit group performs one basic operation of the targeted operation at one cycle. Under the non-contact usage, the basic arithmetic circuit group sequentially performs at least two basic operations of the targeted operation at one cycle.

摘要： The present invention is directed to improve leak analysis resistance by improving randomness of a pseudorandom number. A pseudorandom number generator as a representative embodiment of the invention includes a shift resistor obtained by coupling a plurality of flip flop circuits and can generate a pseudorandom number by shifting signals by the shift register synchronously with a clock signal. A shift amount changing circuit capable of changing a shift amount in the shift register in accordance with a control signal supplied from the outside of the pseudorandom number generator is provided. By changing the shift amount in the shift register in accordance with a control signal supplied from the outside of the pseudorandom number generator by the shift amount changing circuit, it becomes difficult to make outputs of the pseudorandom number generator the same. By using such a pseudorandom number generator, leak analysis resistance can be improved.
