Abstract
This technology relates to an information processing device and an information processing method capable of detecting that at least one of data and a parameter of a command is falsified. A command reception unit of an IC card receives a read command from a reader/writer through an antenna. A MAC calculation unit calculates a MAC based on a read address included in a parameter of the read command and read data to be transmitted to the reader/writer. A response transmission unit transmits the read data and the MAC to the reader/writer through the antenna. This technology is applicable to the IC card, for example.
Claims16
An information processing device, comprising:
- a reception unit which receives a predetermined command from another information processing device;
- a calculation unit which calculates second data for authentication using a same algorithm as the algorithm of the other information processing device based on at least a part of a parameter of the received command and first data to be transmitted to the other information processing device in response to the command;
- and
- a transmission unit which transmits the first data and the second data to the other information processing device.
