The invention discloses a physical layer safe communication method designed by combining signal feedback and artificial noise in a wireless communication network. The method comprises a first stage that a sending end sends information needing to be kept secret to a legal receiving end; a second stage that after the legal receiving end receives the information, a certain amount of artificial noise is mixed in the received information, and the mixed signal is fed back to the sending end; and a third stage that the sending end sends feedback signal to the receiving end. The legal receiving end knows the artificial noise mixed in the second stage, so that the legal receiving end can eliminate the artificial noise; an eavesdropping end cannot eliminate the noise, so that the performance is weakened by the artificial noise; and the safe communication between the sending end and the receiving end is realized. According to the scheme, the safe communication between the legal devices can be realized under the condition that the legal communication devices have no antenna, no external helper and no any channel information of the eavesdropping end.
