Wireless relay transmission system based on physical layer security

Abstract

The invention discloses a wireless relay transmission system based on physical layer security. The wireless relay transmission system comprises a lower cover, a power supply unit, a signal identification unit, a signal receiving unit and a node comparing unit; three signal transmitters are installed at the left end of the lower cover, bolt holes are formed in the right end of the lower cover, and the lower cover and an upper cover are fixedly connected through bolts; and a circuit board on a shock pad is electrically connected with a charging connector through a wire, a signal receiver is connected with an input unit through the signal identification unit, the node comparing unit is connected with a transit transmission controller through a transit transmission processor, and a transit forwarding unit is composed of a decoded signal receiving unit, a signal encryption unit, a signal processing unit and a signal output unit. According to the wireless relay transmission system, marking is conducted when a signal is about to be forwarded, the transmitted signal needs to be identified when the signal is transmitted to another relay point, and then the security needed when the signal is transmitted to the destination is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless relay transmission system based on physical layer security. Background technique [0002] With the rapid development of my country's science and technology and economy since the reform and opening up, it has brought great convenience to people's lives, especially the emergence of communication technology, which has facilitated the communication between people and brought huge benefits to people's lives. Convenience, but the security of wireless calls has received widespread attention. In existing wireless communication systems, encryption techniques are generally used to prevent eavesdroppers from intercepting information from legitimate users. Although encryption technology can improve the security of information transmission, most of these encryption technologies are single encryption, and once multiple of them are cracked, it may lead to the collapse of the en...

Although encryption technology can improve the security of information transmission, most of these encryption technologies are single encryption, once cracking multiple of them may lead to the collapse of the entire transmission system

Therefore, such an encryption method can no longer securely protect communication, and the use of random characteristics of wireless physical information to prevent eavesdropping attacks has attracted widespread attention.
