SATELLITE COMMUNICATION SYSTEM WITH PROTECTION OF THE REMOTE OPERATION MANAGEMENT CHANNEL Russian patent published in 2018 - IPC H04L9/18 

FIELD: active protection device.

SUBSTANCE: invention relates to satellite communication network security. Technical result is achieved by means of a satellite communication system with protection of a remote operation control channel comprising a central earth station (CES) connected via a satellite to user earth terminal (UET). In the satellite communication modem, an additional Ethernet control channel network card has been introduced to receive control commands from CES and to transmit the telemetric information to CES, a cryptographic gateway (CG) has been introduced to the local computer network (LCN) for receiving from the physical interface of the Ethernet modem an encrypted information stream with the purpose of decoding incoming input data, extracting IP packets from them with control commands from CES and routing them to the physical Ethernet interface of the additional network card of the channel, and that is configured to receive a control port IP-packet modem from CES triple modular redundancy modem, stream cipher and its forwarding to data port modem for further transmission to CES. Protection of the satellite communication system is ensured.

EFFECT: technical result consists in strengthening the protection of the satellite communication system.
