Covert channel one-way transmission system based on short-range terahertz communication

Abstract

The invention discloses a covert channel one-way transmission system based on short-range terahertz communication. The covert channel one-way transmission system comprises an outer end machine, a first transmission control card, a terahertz transmitter, a terahertz receiver, a second transmission control card and an inner end machine, the outer end machine is connected with the first transmission control card and is used for receiving file information to be processed; the first transmission control card is connected with the terahertz transmitter and is used for encoding and scrambling the to-be-processed file information to form a to-be-transmitted data packet; and the terahertz transmitter is used for loading the data packet to be transmitted onto a terahertz signal and transmitting the data packet to be transmitted through a terahertz hidden wireless channel. According to the covert channel one-way transmission system based on the short-range terahertz communication, through establishment of the covert channel ferry system of the short-range terahertz communication, the file cross-network exchange efficiency is improved, the security of interactive data is effectively guaranteed, and the data exchange types of an existing system can be enriched; and the data exchange is more convenient on the premise of safety and reliability.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a covert channel one-way transmission system based on short-range terahertz communication. Background technique [0002] In the era of rapid development of information technology, big data applications represented by the Internet have penetrated into all walks of life. While enjoying the convenience brought by the Internet, network security risks are always threatening the security of various connected networks. The government, military, military industry and other units have built business systems and office systems based on internal networks, and the demand for data exchange between secret-related networks of different levels and between secret-related networks and external networks has become increasingly prominent. [0003] At present, confidential data cannot be connected to the public network and public LAN. When transferring data, it is generally transmitted...

AI Technical Summary

Problems solved by technology

[0003] At present, confidential data cannot be connected to the public network and public LAN. When transferring data, it is generally transmitted by manual disk. However, this method is inefficient, poor in security, inconvenient to use, and limited in data types, which cannot meet the current demand scenario.
