TUTORIAL 7 INTRO: Making underwater communications private and authentic
Underwater acoustic communications and networking have made significant leaps forward in recent years. Recent advances include new high-speed communication technologies (achieving a throughput of several tens of kbit/s) as well as communications standards such as JANUS. Common lore on underwater acoustic channels is that they are harsh and affected by significant delay and Doppler spread. In this talk, we will discuss how such “harsh” channels can actually help secure underwater communications by enabling authentication and privacy, both for mildly mobile (e.g., drifting) and intentionally mobile nodes. Moreover, we will present the context and objectives of the NATO SPS SAFE-UComm project, that funded part of our research and is due to end in March 2024.
