Quantum-Resistant One-to-One Communication for Underwater Acoustic Networks

Underwater communication, with its unique characteristics of throughput, delay, error rates, and communicating nodes, often constrained by battery power, presents a significant challenge. In the face of a quantum threat to cryptography, the need to correctly choose quantum-safe cryptographic schemes and key management protocols capable of meeting underwater communication constraints has become crucial. Our paper addresses the topic of securing underwater communication, and more generally, the topic of securing a constrained network. It analyses available post-quantum cryptographic solutions and assesses their applicability to underwater information exchange.
