Secret communication method based on fractional Fourier transform order multiplexing

Abstract

The invention discloses a secure communication method based on fractional Fourier transform order multiplexing, and belongs to the technical field of communication. The method comprises the following specific steps: (1) receiving transmission data and recording data information; (2) carrying out security detection on the transmission data; (3) carrying out encryption processing on the transmission data to generate a communication frame; (4) monitoring a communication security environment in real time; (5) receiving the communication frame and carrying out data decoding on the communication frame. According to the invention, the transmission of violation information can be effectively prevented, the efficiency of maintaining the security and legality of a network environment is improved, the network environment is purified, the requirement of people for surfing the Internet healthily is ensured, the probability of data leakage can be reduced and the data security can be ensured when data is attacked by external personnel in a transmission process, and the security of the data is ensured; and the attack source position can be positioned, so that the personal information security and the public security can be maintained.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a confidential communication method based on a fractal-order flour translation. Background technique [0002] Privacy communication is the scientific and capable branch of information confidential technology in communication. Its specific refers to communication with confidential measures, in addition to confidentiality and other confidentiality measures such as secret, hidden, password, mainly using channel confidentiality and information. Confidential, channel confidentiality is a communication channel that makes the screwdrivers are not easy to cut information. If a dedicated line, instant communication and radio spread communication, information confidentiality is the information confidential code password such as the transmitted information. Transfer, with the development of electronic technology, the confidential machine has been confidential. It is char...

Problems solved by technology

Data confidentiality will cause serious consequences, so data confidentiality has become a very important issue; therefore, it is particularly important to invent a secure communication method based on fractional Fourier transform order multiplexing

[0003] After retrieval, Chinese Patent No. CN108768927A discloses a secure communication method and device. Although this invention is suitable for communication scenarios where the communication bandwidth is narrow and the system time of both parties is deviated, it cannot detect the transmission data sent by the user and cannot effectively prevent The transmission of illegal information cannot maintain the security and legality of the network environment; in addition, the existing secure communication method based on fractional Fourier transform order multiplexing is likely to cause data leakage when attacked by external personnel, which cannot be guaranteed. Data security, and the location of the source of the attack cannot be located, which is not conducive to maintaining personal information security; therefore, we propose a secure communication method based on fractional Fourier transform order multiplexing
