    摘要： A method and apparatus for establishing a secured link between devices. In the establishing of the secured link, a coordinator respectively receives from the first and second devices first pairing information indicating that a first device is to establish a secured link and second pairing information indicating that a second device is to establish a secured link. The coordinator further receives via a first secured link established between the first device and the coordinator shared secured information. The shared secured information is shared between the first and second devices. The coordinator establishes a second secured link with the second device based on the shared secured information; and broadcasts partner notice information indicating that the first and second devices are partner devices. The broadcast partner notice information is then used to establish a third secured link.

    摘要： A visible light communication system and method for transmitting and receiving an information symbol in a visible light communication system for a Color Code Modulation (CCM) scheme using a chromaticity diagram. The method includes determining a first coordinates value corresponding to an information symbol to be transmitted on the chromaticity diagram; determining a first color ratio corresponding to the first coordinates value; determining a second coordinates value corresponding to a compensation symbol for compensating for the first color ratio into a color white and determining a second color ratio corresponding to the second coordinates value; and emitting a visible ray corresponding to each of the first color ratio and second color ratio. The first and second coordinates values are located on a line on the chromaticity diagram.
