Abstract

The invention provides a method and a device for controlling interference signal transmission, and the method comprises the steps: building an optimization model according to a first probability of successful connection of a first link and a second probability of secret interruption of the first link, and enabling the first link to be a link between a transmitting node and a receiving node; determining interference power through the optimization model; and controlling the transmitting node to transmit an interference signal according to the interference power so as to interfere with a second link, wherein the second link is a link between the transmitting node and an eavesdropping node. According to the invention, the problem of low security of the wireless energy-carrying Adhoc network issolved, and the effect of improving the network security is further achieved.

Description

Technical field[0001]The present invention relates to the field of communications, and in particular to a method and device for controlling the emission of interference signals.Background technique[0002]The openness of wireless channels and the broadcast characteristics of electromagnetic signals pose great challenges to the security of wireless communication systems. Traditional secure communication methods are mainly based on modern cryptography, using complex encryption algorithms and keys to encrypt information, such as key management, digital signatures, identity authentication and other technologies. However, with the substantial improvement of computer performance, methods based on cryptography can no longer guarantee absolute security.[0003]In order to improve the confidentiality of information transmission, the source node adopts full-duplex technology. While sending useful signals, it sends interference signals to reduce the channel quality of the eavesdropper’s channel an...
