Problems solved by technology

[0003] Since underwater sensor nodes are all deployed in vast unknown or hostile waters, the physical security of the nodes cannot be guaranteed
The enemy can determine the location of the emission source by listening to the transmission channel, thereby destroying or capturing the node, and cracking the data and keys stored in the node; In the absence of necessary security measures in the domain communication system, the communication network will use the captured node as a normal node, which will cause threats and damage to the entire network
[0004] In view of the many threats faced by the air-sea cross-domain communication network, the existing cross-domain communication system does not consider the security of information transmission

Embodiment Construction

[0043] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] The air-sea cross-domain communication gateway is a device that combines water communication with underwater communication, completes the return of underwater situation information and detection data, the distribution of command and control information, and opens up the water-underwater communication link. When transmitting information between air-sea cross-domain communication gateways, factors such as the rate, bandwidth, a...

Abstract

The invention discloses a data security transmission method based on an air-sea cross-domain communication gateway and a storage medium, and the method comprises the steps: splitting to-be-sent data into n data packets when the data needs to be sent; selecting at most n data transmission links from a plurality of links of the access gateway by using a preset transmission link allocation strategy; and sending the n data packets through the at most n data transmission links. According to the method provided by the invention, data splitting is realized, and the data are transmitted through a plurality of data transmission links, so that the data transmission security of the air-sea cross-domain communication gateway is effectively improved.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a data security transmission method and a storage medium based on an air-sea cross-domain communication gateway. Background technique [0002] At present, air-sea cross-domain communication needs to be completed by applying comprehensive networking of multiple communication methods. Overwater nodes can use satellite communication / short wave / ultrashort wave and other methods for data interaction, while underwater nodes rely on limited means such as underwater acoustic communication / underwater optical communication for network connection. [0003] Since underwater sensor nodes are all deployed in vast unknown or hostile waters, the physical security of the nodes cannot be guaranteed. The enemy can determine the location of the emission source by listening to the transmission channel, thereby destroying or capturing the node, and cracking the data and keys stored...
