The researchers propose a unified communications framework integrating software-defined radios, software-defined networks, and existing satcom infrastructure to create more resilient, efficient, and reconfigurable maritime communications systems, particularly for naval applications 1:47.
Key Takeaways:
• Maritime communications face significant challenges including legacy systems with limited bandwidth, vulnerabilities, and increasing data demands from modernization efforts 1:47-2:42
• Software-defined radios replace fixed hardware functionalities with software platforms, enabling agility, cost savings, rapid prototyping, and enhanced security 4:37-7:26
• Software-defined networks centralize network control, enabling dynamic path selection, traffic prioritization, and seamless link failover 8:41-9:54
• The unified framework applied to carrier strike groups would reduce latency from 552ms to 0.17ms for inter-vessel communications and enable resource sharing through the carrier's larger bandwidth connection 17:40-18:54
• The framework could mitigate known maritime vulnerabilities including AIS spoofing, GPS jamming, and weak VSAT security through improved filtering, multi-sensor validation, and network segmentation 22:15-23:12
The proposed unified framework offers theoretical improvements to maritime communications but requires further simulation and prototype testing to validate its real-world benefits 23:18-24:16.

All right. Uh, everybody, thank you so much for taking time to come to this talk. We hope you have a good time. My name is Ain Shriniasan. I'm an associate professor in the cyber science department at the US Naval Academy. >> And I'm Commander Brian Ctoau. I'm also at the US Naval Academy in the cyber science department. [Applause] >> Thank you. So uh today we would like to present an idea that we have envisioned about resilient and reconfigurable maritime communications and walk you through what we have thought. Uh this p idea that we are presenting comes from a paper that has all been published in the network's journal and my co-authors on that publication are Nadia Nikknami Kenneet Singh German and Juu. So quick disclaimer uh the views expressed in this presentation are those of the aut…
