Abstract

Due to the complexity of wireless communication networks and the open nature of wireless links, complex upper layer network encryption cryptographic algorithms are also difficult to implement effectively in complex mobile wireless communication and interconnection networks, and traditional cryptography-based security policies are gradually not well able to meet the security management needs of today’s mobile Internet information era. In this paper, the physical characteristics of the channel in the wireless channel are extracted and used to generate keys, and then, the keys are negotiated so that the keys generated by the two communicating parties are identical. Then, the generated keys are used by the communicating parties to design the interleaving matrix for encryption of the message. The false bit rate of the system is investigated for the case of an interleaving matrix generated using different quantization methods of keys. The problem of characterizing the encoding and encryption techniques for interleaving keys for the physical layer sensing antenna arrays of wireless channels is studied in depth. The physical layer wireless channel interleaving technique and the wireless channel physical layer encryption technique are organically combined, and a joint interleaving encryption method based on the physical layer key of the wireless channel is designed and used to encrypt and randomize the physical layer data information of the OFDM (Orthogonal Frequency Division Multiplexing) system, which improves the security and reliability of the wireless channel information transmission. The effect of physical layer keys under different physical layer quantization methods on the performance of the wireless channel interleaving encryption algorithm is studied, and the quantization methods of pure amplitude, pure phase, and joint amplitude phase are investigated for the characteristics of wireless physical layer channels.

Summary

Introduction

The Internet has developed rapidly in just a few decades, and in recent years, the emergence of various wireless devices has driven the development of wireless communication. Because of the open nature of wireless broadcasting, resulting in a great security problem of user information, all devices can cross the authorized users directly into the existence of vulnerability of the wireless network or directly on the user information. Because of the open nature of wireless broadcasting, resulting in a great security problem of the user’s information, all devices can cross the authorized user directly into the existence of vulnerabilities in the wireless network or directly to the user’s information eavesdropping and cracking, causing a great threat to the security of information. The method of encrypting the information only by passwords does not guarantee that the eavesdropper will not tap the secret key, and if the eavesdropper steals the secret key, the user’s information security is very threatening [3]
