| 20090144550 | METHOD AND SYSTEM FOR SECURE COMMUNICATION IN NEAR FIELD COMMUNICATION NETWORK - Disclosed is a method for secure communication between a plurality of electronic devices in a Near Field Communication (NFC) network, and a system for supporting the method. To this end, a first electronic device shares a plurality of keys with the at least one device among the plurality of electronic devices and selects a first key among the plurality of keys and exchanges data encrypted based on the first key with the at least one device among the plurality of electronic devices and replaces the first key with at least one key among the plurality of keys while exchanging the data after at least one predetermined criterion has been satisfied. | 06-04-2009 |
| 20090241186 | Method for removable element authentication in an embedded system - The present invention proposes a method for protecting and monitoring removable entities in an embedded system. In accordance with the present invention, prior to insertion of a removable entity in the embedded system, a user registers details of the removable entity in the device host. The details may be entered after entering a password or a PIN. A registration identification is calculated based on an algorithm in the device host and is then stored in the host. After the removable entity is inserted, it is registered in an unalterable area (e.g. flash memory) of the device host. Information such as the category of the removable entity, a device number, etc. may be exchanged between the device host and the removable entity. The device host then computes a registration identification based on a Removable Entity Registration Algorithm. The identifications are then compared, and the device host displays the details of the removable entity to the user. | 09-24-2009 |
| 20090325484 | METHOD AND SYSTEM FOR MANAGING DATA IN A NEAR FIELD COMMUNICATION NETWORK - 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. | 12-31-2009 |
| 20100299527 | NEAR FIELD COMMUNICATION (NFC) DEVICE AND METHOD FOR SELECTIVELY SECURING RECORDS IN A NEAR FIELD COMMUNICATION DATA EXCHANGE FORMAT (NDEF) MESSAGE - 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. | 11-25-2010 |
