SYSTEM AND METHOD FOR ENHANCEMENT OF PHYSICAL LAYER SECURITY IN COGNITIVE RADIO NETWORKS

摘要

PURPOSE: A physical layer security reinforcement system and a method thereof are provided to generate interference for a wiretapping signal of a wiretapping device by using a signal transmitted from a second transmitter through a frequency reuse method. CONSTITUTION: A first receiver(310) receives a signal transmitted from a first transmitter. A wiretapping device(330) wiretaps a signal transmitted from the first transmitter to the first receiver. A second transmitter(340) reinforces the security of a signal transmitted to the first receiver by generating interference for a wiretapping signal of the wiretapping device by using signal transmission through a frequency reuse method. A second receiver(350) receives the signal transmitted from the second transmitter.
