Abstract:
A method of transmitting secret information in a transmitting end and a method of receiving secret information at a receiving end, based on multi-input multi-output (MIMO) multiplexing using antennas, are provided. The method of transmitting includes selecting one or more indices of the secret information that correspond to at least one receiving antenna among receiving antennas, and mapping the one or more indices to an information vector. The method of transmitting further includes precoding the information vector based on channel information between transmitting antennas and the receiving antennas, and beamforming the precoded information vector, using the transmitting antennas.
