Abstract: A data processing apparatus is provided which is capable of improving the responsiveness of communication in which only a maximum of one access request source has write authorization and the other access requests do not have write authorization when communication is performed with a plurality of access request sources. A management apparatus transmits, to a secure application module (SAM), a strong connection request requesting the obtainment of write authorization into the SAM.

The front end gives different time slots for communication to the plurality of elements at the time of activation.

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.

Abstract: The present invention relates to a communication system and communication method, an information processing apparatus and method, a device, a program, and a recording medium with which information communication can be performed securely and very conveniently by a simple configuration. In a secret-key storage unit 101 of a reader/writer 100, a plurality of keys are stored, and identifiers identifying these keys are sent to an IC card 200. The IC card 200 reads a secret key corresponding to a received identifier, encrypts a random number generated by a random-number generating unit 202, and sends the encrypted random number to the reader/writer 100. The reader/writer 100 reads the secret key stored in the secret-key storage unit 101 and corresponding to the identifier sent earlier to the IC card 200, and decrypts the received encrypted random number. The present invention can be applied to, for example, an apparatus that performs communication according to the NFCIP method.
