Abstract:
A method and an apparatus for validating device-to-device (D2D) communication devices in a server via a mobile terminal are provided. A 1st device-to-device (D2D) communication device includes a communication unit for communicating with a mobile terminal via D2D communication, and a controller. The controller is configured to control the communication unit to transmit digital signature information of the 1st D2D communication device to the mobile terminal, receive, when the digital signature information is successfully authenticated in a server, server public encryption information, from the mobile terminal, and transmit device information of the 1st D2D communication device, which is encrypted using the server public encryption information, to the server, and register the 1st D2D communication device in the server. The method and apparatus reduce user input for registering D2D communication devices in a server, increases user convenience, and decrease authentication time.
