Data processing method and device based on file system in satellite

Abstract

The invention provides a data processing method and device based on a file system in a satellite. The method comprises the steps of receiving a data operation request sent by a user terminal; extracting to-be-executed data in the data operation request sent by the user terminal according to the data operation request sent by the user terminal; determining a target storage block corresponding to the to-be-executed data according to the extracted to-be-executed data; obtaining an authentication code corresponding to the target storage block, and authenticating the target storage block by using the authentication code; and if the authentication is passed, responding to the data operation request. According to the embodiment of the invention, after the target storage block is determined according to the data operation request, the target storage block is authenticated, and the data operation request is responded after the authentication is passed; and data leakage or illegal tampering is effectively prevented.

Description

technical field [0001] The present application relates to the field of satellite technology, in particular, to a data processing method and device based on a file system in a satellite. Background technique [0002] Satellite data is sensitive and needs to be protected, not only to prevent illegal users from obtaining information, but also to prevent legitimate users from obtaining unauthorized data. [0003] The satellite system includes satellites in the air and ground stations on the ground. The ground stations communicate with the satellites and are responsible for sending control commands to the satellites and receiving data returned by the satellites. Its ground station is equipped with a satellite operating platform, through which the satellite can be controlled. like figure 1 Shown is a frame diagram of the file system of the satellite system provided by the prior art. The file system is set on the satellite and includes a control module and a memory, wherein the m...

Problems solved by technology

[0004] Because the previous satellites were controlled by government departments and the military, although the file system in the satellite system has no data security protection, the ground station and the satellite are not connected to the external network, so it is difficult for illegal users to enter or access the control system. The ground station of the satellite, the authority of the legitimate user is also strictly controlled, so that the user cannot steal or tamper with the satellite data in the file system through the ground station

[0005] However, with the liberalization of commercial aviation in 2016, commercial satellites have developed rapidly. Some commercial satellite companies allow users to communicate with satellites through ground stations, and some commercial satellite companies allow users to communicate with satellites through the Internet. However, due to the The file system of has no data security protections, allowing users to obtain or tamper with satellite data in the file system
