Abstract

The invention relates to the technical field of secret communication, in particular to a communication system for encrypting information through a chaotic signal. The communication system comprises a signal transmitting end and a signal receiving end, wherein an analog signal input port and an antenna A are arranged on a shell of the signal transmitting end; an analog signal output port and an antenna B are arranged on a shell of the signal receiving end; an A/D conversion module, a chaotic signal generating module, an FM-DCSK (Frequency-Modulated Differential Chaos Shift Keying) modulation module, a radiofrequency modulation module and a power transmitting module are arranged in the shell of the signal transmitting end; a filtering and amplifying module, a radio frequency demodulation module, an FM-DCSK demodulation module and a D/A conversion module are arranged in the shell of the signal receiving end; encryption processing of an input signal is realized through the signal transmitting end; and decryption of received encrypted information is realized through the signal receiving end. Through adoption of the communication system, the problem of poor secrecy in current wireless communication is solved, and chaotic encryption processing of transmitted signals is realized, so that the security and reliability of wireless communication are enhanced.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to a communication system for encrypting information through chaotic signals. Background technique [0002] At present, with the rapid development of communication technology, wireless mobile communication not only facilitates people's daily life, but also improves work efficiency and changes our way of life. However, whether it is digital communication of radio waves or analog communication, there are a series of problems, such as: information security, radio multipath fading problems, broadband communication problems, electromagnetic interference and so on. In particular, the issue of confidentiality in communication is one of the main problems faced in the current communication process. In our daily communication, the SIM card in personal communication is easy to be copied, personal privacy is eavesdropped, and the encryption algorithm in Wi-Fi communication is ofte...
