    摘要: Methods for selectively securing records in a Near Field Communication Data Exchange Format (NDEF) message. A method includes placing a place marker signature record in the NDEF message. The place marker signature record is a modified signature Record Type Definition (RTD). A first set of records preceding the place marker signature record in the NDEF message is unsecured. The method also includes securing a second set of records following the place marker signature record. Another method includes placing a secured bytes field in the signature RTD. The secured byte field indicates a number of bytes of data to be secured preceding this field. The method also includes securing data in records preceding this field in the signature RTD, based on a value of the secured bytes field.

    摘要: A method and system for managing data between a plurality of electronic devices in a Near Field Communication (NFC) network are provided. The method is performed at a first electronic device. A request is received from a second electronic device to send context data. The context data is then represented in accordance with a context Record Type Definition (RTD). The context RTD is used for defining context data in the NFC network. The context data that is represented in accordance with the context RTD is exchanged with the second electronic device.
