Research Of The Application Of Chaotic Encryption In Optical Communication

Chaotic nature of this widespread phenomenon, with its own characteristics, is ideal for confidential communications. Its sensitivity to initial conditions, pseudo-random features and a wide power spectrum of characteristics that a confidential communication has great potential. In the field of telecommunications, optical fiber communication has become a trend. With the rapid development of telecommunications industry, communications, confidential performance, has become indispensable in people's daily life, things that can not be fully and safe security measures to become the people's needs.This paper introduces the concept of Chaos Theory and characteristics of chaos synchronization theory and realization of optical chaos in the development process, cryptography these disciplines, allowing readers to the concept of chaos encrypted optical communication there is a general understanding. Then simply tell the principle of chaotic secure communication technologies, and cited several current common chaotic encryption methods, the security of their systems performance analysis, citing the current chaotic secure communication in several instances, pairs of Chaos on the Laser Communications Research conducted a narrative of progress, giving the readers a general understanding of Chaotic Secure optical communication system. View of the current decoding technology, the rapid development of the old encrypted communication system has been unable to meet the performance requirements of confidentiality. This paper designed two kinds of chaotic modulation based on two chaotic encryption communication system, conducted a Matlab simulation analysis, and its security performance is analyzed, reaching a high degree of confidentiality purposes.
