Communication has become a very important part of people’s work and life. Wireless communication technology has the characteristics of low cost, good scalability, and easy use, but it is vulnerable to eavesdropping and other security threats, and eavesdroppers illegally receive through wireless channels. Traditional wireless communication system security methods need to be implemented at the upper layer through authentication and cryptographic techniques. In recent years, as an important complement to traditional security mechanisms, information theory security principles, transmission signal security technologies, spread spectrum and frequency hopping encryption technologies, and channel coding Research on physical layer security technologies such as encryption technology and modulation encryption can effectively protect information during wireless transmission and prevent eavesdroppers from illegally receiving information.
