Physical layer encryption transmission system and method for wireless communication

Abstract

The invention discloses a physical layer encryption transmission system and method for wireless communication. The physical layer encryption transmission system comprises a construction module, an estimation module and an encryption module which operate on a base station of a multi-input single-output (MISO) wireless communication system; the construction module is used for a construction system;the estimation module is used for channel estimation; and the encryption module is used for encryption sending. The physical layer encryption transmission system for wireless communication further comprises a recovery module running on the legal receiver; and the recovery module is used for recovering the data. In combination with other structures or methods, the defects of low security and greatly reduced communication reliability of physical layer encryption of a multi-input single-output (MISO) wireless communication system against modulation identification and attacks of eavesdroppers in the prior art are effectively avoided.

Description

technical field [0001] The present invention relates to the field of information security technology in wireless communication, and also to the field of framing technology, in particular to a physical layer encryption transmission technology (PLE) in a physical layer security technology (PLS), and in particular to a physical layer encryption transmission technology (PLE) for wireless communication.
