Abstract: The present invention relates to a system and method for issuing an authentication key for authenticating a user in a CPNS environment. The system comprises a user terminal, a gateway and a CPNS device. The user terminal is equipped with a short-range wireless communication function, requests the gateway to register terminal information including an ID and password, encrypts the terminal information including the ID and password using the password, transmits an authentication request signal including the encrypted terminal information to the gateway, and receives an authentication key generated by a CPNS device. The CPNS device stores the terminal information, performs user authentication by decrypting the encrypted terminal information in response to the authentication request, generates an authentication key for the CPNS when a user is authenticated, encrypts the generated authentication key using the password, and transmits the encrypted authentication key to the user terminal through the gateway.

Abstract: The RFID system includes an RFID reader for sending information selected from among collision type information, idle type information, and readable type information, to all of the RFID tags depending on the number of signals in the corresponding time slot, and RFID tags for performing functions, in which, when information, indicating that a current time slot is a collision type, is fed back from the RFID reader, each of RFID tags selects one arbitrary value of either 0 or 1 and is assigned a time slot, in which a corresponding RFID tag will send a signal to the RFID reader, based on the selected value, a single tag group that caused a collision is divided into two sub-groups depending on the assigned time slots, and tags of the sub-groups send signals, including IDs thereof, to the RFID reader in different time slots for the respective sub-groups.

Abstract: The present invention relates to the use of a plurality of dependency trees in tree-based statistical machine translation and proposes a dependency forest to effectively process the plurality of dependency trees. The present invention can improve a translation capability by generating a translation rule and a dependency language model by using the dependency forest and applying the generated translation rule and dependency language model when a source language text is converted to a target language text.
