Mutual Authentication between Ships in the E-Navigation Environment

In recent maritime communication, discussion for the maritime information exchange has been carried out continuously around the e-Navigation for environmental protection and safe navigation. However, it is the situation that is concentrated only in the service and a common data structure for maritime information sharing, security considerations is insufficient. In this paper, we analysis the security threats and vulnerabilities that can be generated in the e-Navigation environment and propose a mutual authentication method to provide reliable communication between ships of e-Navigation. In the proposed scheme, it assures the reliability with each other through mutual authentication before starting AIS communication between ships by utilizing the MMSI is a unique key of ship.
