Abstract
International Association of Lighthouse Authorities (IALA) is developing the standard intersystem VTS exchange format (IVEF) protocol for exchange of navigation and vessel information between VTS systems and between VTS and vessels. VTS (vessel traffic system) is an important marine traffic monitoring system which is designed to improve the safety and efficiency of navigation and the protection of the marine environment. And the demand of Inter-VTS networking has been increased for realization of e-Navigation as shore side collaboration for maritime safety. And IVEF (inter-VTS data exchange format) for inter-VTS network has become a hot research topic of VTS system. Currently, the IVEF developed by the International Association of Lighthouse Authorities (IALA) does not include any highly trusted certification technology for the connectors. The output of standardization is distributed as the IALA recommendation V-145, and the protocol is implemented with an open source. The IVEF open source, however, is the code used to check the functions of standard protocols. It is too slow to be used in the field and requires a large memory. And the vessel traffic information requires high security since it is highly protected by the countries. Therefore, this paper suggests the authentication protocol to increase the security of the VTS systems using the main certification server and IVEF.
Highlights
The vessel traffic system (VTS) field that is about maritime safety has mostly relied on overseas technology, unlike the shipbuilding industry that has recently retained the leader’s position in the global market as a traditional industry
The VTS Committee of International Association of Lighthouse Authorities (IALA) is a framework of methods and services to promote the safety, security, efficiency, and environment protection in all transportable water that is evolving from a traditional VTS to an e-Navigation service
IALA, which is the basic protocol to provide intersystem VTS exchange format (IVEF) service between VTS centers, defines nine messages as shown in the Notions and Acronyms section. Definition of these messages is composed of XML-type schema and all messages are composed of subelements of MSG IVEF, which is the most significant element
Summary
The vessel traffic system (VTS) field that is about maritime safety has mostly relied on overseas technology, unlike the shipbuilding industry that has recently retained the leader’s position in the global market as a traditional industry. There is a trend that VTS has been evolving to vessel traffic management (VTM) recently and VTS’ overall concept has expanded as the framework of the methods and services to enhance the following: the safety in the sailable water, the efficiency in security and shipping, and the marine environment protection. In other words, this service architecture has been changing into a new service. Secure communication systems among the network enabled devices are significant concern in mobile environments [1]
