PROBLEM TO BE SOLVED: To provide a method and a device for transmitting a data stream securely.SOLUTION: The method includes a step for dividing a data stream into a plurality of output sub-streams. Each of the output sub-stream is associated with a spectrum segment of a first carrier signal, and has a data rate compatible with the band width of each spectrum segment. Each spectrum segment is one of the plurality of spectrum segments adapted to be used in connection with the output sub-stream. Each of the plurality of spectrum segments is a spectrum block discontinuous with respect to the plurality of spectrum segments, and is separated from other spectrum segments of the plurality of spectrum segments, by at least an allocated spectrum segment not included in the plurality of spectrum segments.SELECTED DRAWING: Figure 15 |
