  • Publication number: 20230067844
    Abstract: There is provided an information processing apparatus, an information processing method, a program, and an information processing system which make it possible to improve the safety of a time variant key. The information processing apparatus according to one aspect of the present technique receives a first random number and a second random number which are transmitted from another information processing apparatus, generates a third random number, generates a first time variant key by causing the second random number and the third random number to act on a first fixed key, encrypts the first random number by using the first time variant key, and transmits the encrypted first random number and the third random number to the another information processing apparatus. The present technique can be applied to an IC card mounted with an IC chip for performing non-contact communication.

  • Publication number: 20110016373
    Abstract: A system, method, and apparatus for data communication including a transmitter and first processor for data transmission in at least two states of operation, a receiver, memory device, and second processor providing at least two states of operation for processing the data. In a ready state, received data is ready for processing upon reception. In an active state, received data is converted into a different format prior to processing. The transmitter transmits first data associated with the ready state, a first transition command associated with transitioning from the ready state to the active state, second data associated with the active state, and a second transition command associated with transitioning from the active state to the ready state. The second processor processes the first data in the ready state, transitions to the active state, processes the second data in the active state, and transitions to the ready state.
