I hold a master's degree in Information and Communication Systems from Technical University of Hamburg, with a focus on communication networks, digital communication, and security. My current research involves ship-to-shore communication, maritime simulator networks, and situational awareness assessments. With a passion for advancing maritime technologies, I strive to contribute to innovative solutions that enhance safety and efficiency in maritime operations.

Chris Hargreaves works as an R&D Engineer for GRAD: the Research & Development Directorate for the General Lighthouse Authorities of the UK & Ireland. His specialism is resilient position and navigation and he worked for many years on the UKs eLoran programme. Today, he is presenting the work of two of his colleagues who have created the capability to digitally sign Marine AIS messages so that their origins can be authenticated, thus preventing the misleading broadcast of spoofed messages.
