Data transmission method and device, related equipment and storage medium

Abstract

The invention discloses a data transmission method and device, related equipment and a storage medium. The method comprises: by utilizing a flow identifier of the data flow a virtual SPI identifier and a security parameter index identifier (SPI) of an internet protocol security (IPSec) tunnel for transmitting the data flow, determining a virtual SPI identifier; for each encrypted message in the data stream, carrying a virtual SPI identifier in the corresponding message; and transmitting the data stream to a receiving end through the IPSec tunnel, wherein the virtual SPI identifier is used forthe receiving end to send each message of the data stream to the same decryption unit for decryption processing.

Description

technical field [0001] The present application relates to the technical field of network communication security, and in particular to a data transmission method, device, related equipment and storage medium. Background technique [0002] At present, in the fifth generation mobile communication (5G, fitth Generation) network, in order to ensure the security of data transmission, IPSec tunnels are usually used to protect the integrity of data. At present, in order to improve the processing performance of the IPSec tunnel, after the encryption end transmits the data flow to the decryption end through the IPSec tunnel, the decryption end will transmit each message of the data flow to multiple decryption units according to a preset algorithm for decryption processing. [0003] In the above manner, the decryption end uses multiple decryption units to process each packet of the data stream separately, which may aggravate packet disorder. Contents of the invention [0004] In ord...
