Protecting Future Maritime Communication [PDF]

Proceedings of the 12th International Conference on Availability, Reliability and Security, 2017
Our oceans are filled with ships that take care of the most important distribution of goods in the world economy. Evolving from isolated chunks of hollow metal containers, ships are becoming more and more like interconnected floating computers, and thus increasingly exposed to unwanted cyber events. This paper shows how a Public Key Infrastructure (PKI)
