Boatbuilders are seeing more marine electronic manufacturers with Internet-based functions. Many of these electronic manufacturers are using Ethernet. NMEA is close to releasing a new OneNet standard, which is based on Internet Protocol Version 6 (IPV6) and Ethernet IEE 802.3. The OneNet Committee composed of 80 marine electronic manufacturers has produced 11 different but interconnected modules for this new Standard. Cybersecurity has been addressed in the OneNet Standard and includes robust Security Modules containing message authentication, encryption, and certification verification. Also discussed will be other modules including the Physical Layer, Device Discovery, and PGN Transport and Gateway modules.
