Channel scrambling transmission method of active nonlinear transformation

Abstract

The invention discloses a channel scrambling transmission method of active nonlinear transformation. An interference signal incoherent with a signal to be sent serves as a known codebook, nonlinear distortion generated by the codebook is added to the signal to be sent actively, and the codebook and a nonlinear model are transmitted to a partner while the signal is transmitted; a memory nonlinear characteristic is actively added from encryption information is sent, so that the information is hidden in the nonlinear signal which tends to be insignificant, a barrier is provided for an informationreception decision step of a non-partner, and the non-partner has no significance in deciding the reception code. Thus, information is hidden, and further information capturing, recovery and decodingare influenced.

Description

technical field [0001] The invention relates to the technical field of communication security, and more specifically, relates to an active non-linear transformation channel scrambling transmission method. Background technique [0002] The core of communication technology is encryption technology. The memory or non-memory nonlinear phenomenon of electronic equipment and devices and transmission links often becomes one of the key factors that restrict the improvement of system performance and affect the correct reception of signals. The encryption technology developed in traditional cryptography mainly deals with systems with finite integers, and the chaotic secure communication technology developed based on complex dynamics has become a new research hotspot in the past ten years. It has some common features with traditional cryptography, the most important feature is the sensitivity to variable and parameter changes, but the system used in chaotic secure communication is def...

Problems solved by technology

[0006] Aiming at the defects of the prior art, the purpose of the present invention is to solve the problem that the existing wire communication security technology is prone to information leakage due to the crosstalk and radiation of the metal cable, the harmonic radiation of the carrier machine and the eavesdropping of the enemy, and the existing Cryptographic theory-based secure communication technology clearly prompts the attacker or listener which is important information, which is easy to arouse the curiosity and attention of the attacker, increases their desire to attack and crack, and limits the security of the security technology.
