Embodiment Construction

[0023] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0024] like figure 1 and figure 2 As shown, the present invention relates to a unidirectional transmission method based on a virtual receiver.

[0025] In order to achieve the above purpose, the present disclosure provides a one-way transmission method based on a virtual receiving end. First, a set of public and private keys of RSA asymmetric encryption is generated, a public key file is built in the client of the transmission system, and the virtual receiving end and the single The private key file is built into the receiver. The one-way receiving end obtains the split traffic data packets through the packet capture technology, and then performs CRC verification,...

Abstract

The invention discloses a one-way transmission method based on a virtual receiving end. The client is connected to the virtual receiving end and the one-way receiving end through a light splitting device, and the client establishes a two-way connection with the virtual receiving end, that is, the client sends the virtual receiving end to the virtual receiving end. TCP connection, the client establishes a one-way connection with the one-way receiver, the information transfer from the client to the one-way receiver is one-way, and the one-way receiver will not have any active data communication between the client and the virtual receiver. Helps prevent data leakage.

Description

technical field [0001] The invention relates to the technical field of data transmission security, in particular to a one-way transmission method based on a virtual receiving end. Background technique [0002] File transfer is a network function that is widely needed in the current Internet, such as uploading and downloading files to cloud disks, uploading file attachments to application systems, and file transfer in the scenario of internal and external network isolation. [0003] However, when transferring files over the Internet, due to the openness of the network, it often brings some network security problems, such as malicious transfer of illegal files, man-in-the-middle attacks, interception of transferred files, tampering of transferred files, etc. Attack and control the server. In some scenarios with high data security requirements, it is necessary to ensure that files are kept confidential to others, that files transmitted to the server are trusted, and that the s...
