	abstract = {The Covid-19 pandemic brought a problem related to the inability to timely update security systems on ships during a voyage and the need to encrypt data stored in ship information systems (SISs) and shipping company information systems. The analysis of new types of worldwide cyberattacks showed that they were set off by an increase in the use of remote-controlled autonomous technologies and a spread of telework. It was proved that on ships: a) there are no cybersecurity specialists; b) there is no means of identification of cyber threats and no response plans; c) there is a lack of cybersecurity training for crews; d) encryption of confidential ship data is barely used; e) crew is a vulnerability factor in ship's security. The analysis of cyber incidents allowed us to develop a basic response plan to protect ship control systems. It was demonstrated that the basic plan can be continuously updated and improved in accordance with: a) the real state of ship systems; b) the results of performance analysis of crew actions; c) the emergence of new types of cyberattacks. To improve the security of confidential data in ship information networks theoretical framework for the development of encrypted data search engines with the identification of â€sdangerous” keywords for the ship information systems (SISs) was proposed. A data exchange protocol, basic requirements for SISs, and an algorithm for detecting â€sdangerous” keywords in messages were developed. A test search engine on encrypted data was presented, and the main components of the system were highlighted. The functionality of the system was experimentally proved, and the accuracy and speed of search on encrypted data were determined.},
