    • The present invention relates to an information processing apparatus that allows separately forming regions having different roles. When an area definition region #0100h is newly formed under an area definition region #0000h that is formed on an IC card, information of the area definition region #0100h is encrypted using a service key stored in an area registration service definition region #0020h that is formed in advance, and the encrypted information is supplied to the IC card. Upon receiving that information, the IC card decrypts the encrypted information using the service key stored in the area registration service definition region #0020h. Then, the area definition region #0100h is formed based on the result of decryption. The present invention may be applied to an IC card that exchanges information in a non-contact manner and to an apparatus that exchanges data with the IC card.
    • 本发明涉及允许分开形成具有不同作用的区域的信息处理设备。 当在形成在IC卡上的区域定义区域#0000h下新形成区域定义区域#0100h时,使用存储在区域注册服务定义区域#0020h中的服务密钥对区域定义区域#0100h的信息进行加密, 并且将加密信息提供给IC卡。 在接收到该信息时,IC卡使用存储在区域注册服务定义区域#0020h中的服务密钥来解密加密信息。 然后,基于解密结果形成区域定义区域#0100h。 本发明可以应用于以非接触方式交换信息的IC卡和与IC卡交换数据的装置。

    • The present invention relates to a communication system and communication method which enable various types of near field communication, and a data processing apparatus. NFC communication apparatuses 1 to 3 have two features in that each can perform communication in two communication modes and that each can perform data transmission at a plurality of transfer rates. The two communication modes consist of a passive mode and an active mode. In the passive mode, between the NFC communication apparatuses 1 and 2, for example, the NFC communication apparatus 1 transmits data to the NFC communication apparatus 2 by modulating electromagnetic waves generated by itself, while the NFC communication apparatus 2 transmits data to the NFC communication apparatus 1 by performing load modulation on the electromagnetic waves generated by the NFC communication apparatus 1. Alternatively, in the active mode, either of the NFC communication apparatuses 1 and 2 transmits data by modulating electromagnetic waves generated by itself. The present invention can be applied to, for example, an IC card system, etc.
    • 本发明涉及能够进行各种类型的近场通信的通信系统和通信方法,以及数据处理装置。 NFC通信设备1至3具有两个特征,每个功能可以以两种通信模式执行通信,并且每个可以以多个传输速率执行数据传输。 两种通信模式由被动模式和活动模式组成。 在被动模式中,NFC通信装置1例如NFC通信装置1通过调制自身产生的电磁波向NFC通信装置2发送数据,而NFC通信装置2向NFC通信发送数据 装置1通过对NFC通信装置1产生的电磁波进行负载调制。 或者,在活动模式中,NFC通信装置1和2中的任一个通过调制由其自身产生的电磁波来发送数据。 本发明可以应用于例如IC卡系统等
