Embodiment approach

[0101] In a possible implementation manner, the one-way visible light unit 702 is also used for:

[0102] Decode the forward error correction code and verify whether the decoded message is the same as the encrypted message;

[0103] When the decoded message is the same as the encrypted message, use the decoded message as an encrypted message, use a private protocol to decrypt the encrypted message, and obtain valid information in the access request;

[0104] When the decoded message is different from the encrypted message, the forward error correction code data recovery method is used to recover and decrypt the decoded message to obtain valid information in the access request.

[0105] In a possible implementation manner, the one-way visible light unit 702 is also used for:

[0106] Receive the forward error correction code and unpack it, and obtain the set of encoded packets corresponding to the forward error correction code;

[0107] Determine whether the number of encoded...

Abstract

The invention relates to the technical field of information security, provides a data transmission method and system based on visible light and a storage medium, and is used for solving the technical problem that high-security transmission of data between networks with different security levels cannot be realized in an absolute physical unidirectional isolation network environment in the prior art. The method comprises the following steps: performing encryption and forward error correction code processing on an access request received in a first security level network to obtain a forward error correction code corresponding to the access request; transmitting the forward error correction code to one end connected with the second security level network through one-way visible light, and restoring effective information in the access request from the forward error correction code; and initiating access to the second security level network according to the effective information.

Description

technical field [0001] The patent of the present invention relates to the field of information security technology, in particular to a method, system and storage medium for data transmission based on visible light. Background technique [0002] With the development of informatization, for security reasons, networks in many important areas are physically isolated to ensure network security in core areas. [0003] The so-called "physical isolation" means that there is no direct physical connection between networks with different security levels at any time, and each network is an independent information island, so as to ensure the information security of each network. However, in real life, people often need to exchange data between networks with different security levels. At this time, it is necessary to ensure the safe transmission of data between networks with different security levels on the basis of absolute one-way data transmission. [0004] In the prior art, network g...
