Design Challenges and Implementation of a Shipborne Gateway for Safe and Secure Navigational Networks

As the shipborne system becomes more complex by integrating more shipborne equipment through a network, the safety and security for the navigational system becomes an important issue. In this paper, we address some design challenges and issues for the design of safe navigational networks including cyber security. In addition, we introduce the safety and security system for navigational networks. Finally, we implement a security shipborne gateway system to interconnect with safe and secure navigational networks.
