Abstract: The method comprises registering at least one of an internet protocol (IP) address and a media access control (MAC) address of the security devices, generating a plurality of public key and private key pairs, encrypting and storing private keys comprised in the plurality of public key and private key pairs using a master key provided from a master key management unit, selecting any one of a plurality of public key and private key pairs when the access of the security device is approved and providing a certificate comprising the selected public key to the security device, receiving a symmetric key encrypted with the public key of the certificate from the security device, and decrypting the private key using the master key provided from the master key management unit.

Abstract: A method for configuring an observable object as a digital twin in a digital twin system of any one domain is provided. The method for configuring a digital twin includes defining a purpose for expressing the observable as a digital twin in the domain, organizing data based on a role of the observable object in the domain, configuring the observable object into the digital twin based on the data for the purpose, and synchronizing the observable object and the digital twin.

Abstract: A method and terminal for receiving and processing traffic information and a method and apparatus for providing the traffic information, where the method for receiving traffic information includes reading region information included in received traffic information, determining whether a first region indicated by the region information overlaps with a second region corresponding to location information on which traffic information is desired, and decoding the traffic information including the region information indicating the first region if the determination result indicates that the first and second regions overlap.

Abstract: A terminal including a position-location module configured to receive position information of the terminal, and a controller configured to control an operation of the position-location module, and synchronize position relevant information obtained using the position information received by the position-location module with user schedule information.

Abstract: A method and terminal for receiving and processing traffic information and a method and apparatus for providing the traffic information are disclosed. According to an embodiment, the method for receiving traffic information includes reading region information included in received traffic information, determining whether a first region indicated by the region information overlaps with a second region corresponding to location information on which traffic information is desired, and decoding the traffic information including the region information indicating the first region if the determination result indicates that the first and second regions overlap.

Abstract: A method and apparatus for receiving or providing traffic information are disclosed. The method for receiving the traffic information according to an embodiment includes receiving the traffic information, determining whether version information of the received traffic information is identical to version information of previously stored traffic information, and decoding the received traffic information if the version information of the received traffic information is not identical to the version information of the previously stored traffic information.
