The invention provides an online update and protection method for VDES electronic chart data. The technical solution of the invention is to update the electronic chart data online on the VDES, and a VDES electronic chart data transmission protocol is designed. In the process of VDES system transmitting electronic chart data, in order to ensure the security of transmission, a mixed encryption system security mechanism based on AES and ECC is proposed for shore and ship. In view of the shortcomings of DSA in the existing electronic chart protection scheme, the S-63 electronic chart data protection scheme is optimized, and the ECC algorithm electronic chart data signature mechanism is designed. The invention uses ECC encryption technology and digital signature technology which are safe, efficient and have lower bandwidth requirements, and effectively improves the security, high efficiency and bandwidth requirements of the S-63 electronic chart data protection scheme. At the same time, a security guarantee mechanism and a chart data update protocol have been built for VDES electronic chart services to ensure the security and reliability of online transmission and update of electronic chart data.
Description
technical field [0001] The invention relates to the technical field of VDES electronic chart data transmission, in particular to an online update and protection method for VDES electronic chart data. Background technique [0002] Both officially authorized electronic chart data service providers and ECDIS equipment manufacturers attach great importance to protecting their own chart data information. However, the current S-63 electronic chart data protection scheme and real-time transmission and update of electronic chart data or There are more or less certain disadvantages. In the S-63 electronic chart data protection scheme, the efficiency of DSA digital signature algorithm decreases with the increase of electronic chart data and the limitation of communication bandwidth, and the real-time performance of data information cannot be guaranteed. The VHF Data Exchange System (VDES) is a new generation of maritime communication system under the e-Navigation framework. Its main ...
