Security Enhancement of Maritime Cloud

Abstract
The Maritime Cloud is the term used to describe the concept of an infrastructure that support authorized, seamless information transfer, as requested by the IMO e-navigation strategy, and as derived from testbeds focused on e-navigation. This paper proposes a lightweight user authentication protocol where the Message Queue Telemetry Transport type protocol registers unique topic values from the user to send the value to a server through the QoS(Quality of Service) 2 method and lightweight usage information measurement protocol where the transmission of usage information for communication service measurement consumes less mobile device resources..
