Research on Key Technologies of ship network security protection

With the improvement of smart ship, control system of ship, communication and navigation system, information management system and equipment are gradually interconnected through the network, and the ship has more and more frequent contact with the outside world. However, more and more ships are “online”, which leads to the increasingly serious problem of network security. In order to comprehensively improve the ship’s network security protection capability, this paper fully investigates the latest scientific research achievements and industry practical experience in the field of ship network security. Aiming at the hidden dangers of network security in ship key information systems, the research on the overall protection route of ship network security has been carried out. Based on the research of key technologies such as ship network boundary protection technology and ship data security encryption technology, a multi-level security protection system of ship network is constructed, and a complete and popularized ship network security protection solution is formed.
