Security of underwater acoustic communication based on hypergraphs

Underwater acoustic communication faces challenges such as multipath effects, high latency, and narrow bandwidth in complex ocean environments, with its security severely threatened by eavesdropping, interference, and camouflage attacks.This paper proposes a security enhancement method for underwater acoustic communication based on hypergraph theory, applying hypergraph theory to the security field of underwater acoustic communication. By constructing an underwater acoustic communication hypergraph model, it analyses its topological characteristics and designs corresponding security strategies. Experiments demonstrate that the hypergraph-based method can effectively improve the security of underwater acoustic communication, showing significant improvements in bit error rate, interference resistance, and security compared to traditional schemes, providing new insights for marine information security.
