VSAT remote station baseband equipment data processing method based on encryption and decryption

Abstract

The invention discloses a VSAT remote station baseband equipment data processing method based on encryption and decryption. Data conversion is performed on intermediate frequency input data by four paths of parallel modulator-demodulators by adopting a TPC code, and data generated via conversion are stored in a database server; classification is performed in the database server and the data are outputted to a decryption machine to be decrypted; the decrypted data are outputted to a classification terminal server in which identifiable telephone voice, IP data, IP voice or fax data are generated; and telephone voice, the IP data, IP voice or the fax data are encrypted via an encryption machine and then integrated into frames via the modulator-demodulators and outputted. The intermediate frequency input data are processed into telephone voice, the IP data, IP voice or the fax data which can be identified by users so that available and important data can be timely analyzed by remote station work personnel, security of data transmission is also guaranteed and thus information divulgence is avoided.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a data processing method of a VSAT remote station baseband device based on encryption and decryption. Background technique [0002] VSAT (Very Small Aperture Terminal) is a satellite communication earth station with a small antenna aperture, also known as a miniature earth station or a small earth station. It is characterized by a small antenna diameter (generally 0.3-2.4 meters), compact equipment, Solid, intelligent, cheap, easy to install, not demanding on the use environment, and not limited by the ground network, flexible networking. The VSAT satellite communication system consists of two parts: space and ground. The space part is the satellite, and the ground part is composed of gateway stations, remote stations and network control units. The remote station is the main body of the satellite communication network, and the VSAT satellite communication network...
