Digital phonetic chaotic secret communication system

Abstract

The digital phonetic chaotic secret communication system consists of phonetic coding circuit and phonetic decoding circuit, and features that the phonetic coding circuit encodes the phonetic signal into electronic signal, the chaotic modulator completes the signal modulation, the chaotic demodulator demodulates the received signal and the phonetic decoding circuit decodes and output the signal.

Description

Technical field: [0001] The invention relates to a communication system, in particular to a digital voice chaos security communication system. Background technique: [0002] In the existing technology, the security technology used in communication is mainly realized by encoding, and through the linear or nonlinear transformation of the information codeword, the information will not be cracked during the transmission process, but when this technology is actually used, Since the detecting party can search according to the encoding rules of the codeword, most of them can be decrypted under long-term calculation, which affects the confidentiality of communication. Invention content: [0003] The technical problem to be solved by the present invention is: in the prior art, the security technology used in communication is mainly realized through encoding, and through the linear or nonlinear transformation of the information codeword, the information will not be cracked during th...
