Optical access encryption method based on multi-frequency sine chaos neural network

Abstract

The invention relates to an optical access encryption method based on a multi-frequency sine chaos neural network. Through the multi-frequency sine chaos neural network, a key library with a great space is generated, and multiple encryption processing is performed on original data, so compared with a traditional encryption mode, the complexity of a chaos model is further enhanced; while the information sending cost is reduced, the information transmission security is greatly enhanced, and an eavesdropper can be effectively prevented from brute force cracking through big operation. According to the invention, in a one-time one-password encryption mode, the security and flexibility of communication transmission can be greatly enhanced.

Description

technical field [0001] The invention belongs to the communication field and relates to an optical access encryption method based on a multi-frequency sinusoidal chaotic neural network. Background technique [0002] Nowadays, optical fiber communication systems of various speeds have basically replaced the original cable communication and become the main means of information transmission in the telecommunication network. At the same time, the security of information transmission has been paid more and more attention. , as large as the country's data information, there is a possibility of being stolen if you are not careful. Information encryption is an effective means to ensure the security of information transmission, such as processing signals from the information source to achieve symmetric encryption, monitoring and encrypting channels from the information transmission path, and encrypting from the modulation method of the signal. At present, the more secure encryption m...

Problems solved by technology

At present, the more secure encryption method is "one-time encryption", that is, each time information is sent, there is a different encryption key. However, in the face of such a huge amount of data, it is often difficult to transmit and distribute. Traditional cryptography The era of information explosion is powerless, and due to the emergence of large-scale computers, the calculation speed is getting faster and faster, resulting in the need for continuous updating of the encryption scheme, and the continuous increase of the key space capacity and its confidentiality performance, so it is urgently needed. An encryption scheme that can realize large-capacity key distribution
