Abstract: Disclosed are a secure communication device and a secure communication method using an artificial noise scheme. The secure communication method between a multi-antenna legal transmission device and a multi-antenna legal reception device includes determining a power allocation ratio for a system parameter, by the legal reception device, generating a transmission signal including a secret information message based on the determined power allocation ratio and artificial noise, and transmitting the generated transmission signal to the legal reception device.

Abstract: A method and apparatus for generating a secret key includes: acquiring a random sequence by use of reciprocity of a radio channel; generating the secret key based on the random sequence; and stopping generating the secret key when it is determined that the radio channel is flat based on flatness measured from the radio channel.
