Symmetric Encryption Method Based on Artificial Baseband Noise Based on Digital Baseband Signal

Abstract

The invention provides a symmetric encryption method of artificial baseband noise based on digital baseband signals, which first generates artificial baseband noise signal sequences; then performs artificial baseband noise encryption at the legal sending end; finally uses the cross-correlation in data mining at the legal receiving end The comparison method algorithm is used to locate and decipher the artificial baseband noise. The present invention directly performs completely random interference / encryption of the artificial noise baseband signal sequence on the digital baseband signal of the legal sending end, and utilizes an algorithm to dejamming / decryption at the legal receiving end. Since it is directly interfered and designed on the digital baseband signal, It can well solve the problem of using analog signal interference in the prior art and requiring signals that cannot be synchronized in different hardware devices, which greatly makes the present invention not bound by hardware limitations and the environment of encrypted signal transmission, so that it can It is generally used in wireless network transmission environments and has real practical deployment capabilities.

Description

technical field [0001] The invention belongs to the field of physical layer security solutions for wireless network communication, in particular to a symmetric encryption method based on artificial baseband noise of digital baseband signals. Background technique [0002] In the existing wireless network information security technology, the symmetric / asymmetric encryption algorithm in modern cryptography still occupies a dominant position. By using symmetric (such as: DES, AES, etc.) or asymmetric (such as: RSA, DSA, etc.) encryption algorithms for the upper layer of the wireless network to ensure the security protection of the transmitted information. Generally speaking, since the eavesdropping / attacking party does not know the key used to encrypt the information, it becomes very difficult for the eavesdropping / attacking party to crack or forge the encrypted ciphertext. Unfortunately, with the development of cryptanalysis (cracking technology), especially the proposal of br...
