Protect submarine communications, sonar data pipelines, underwater acoustic networks, and subsea sensor systems against quantum computing threats. From PQC-encrypted acoustic modems to AI-powered sonar classification with quantum-safe integrity across every underwater defense layer.
PQC-encrypted underwater acoustic communications using ML-KEM key exchange integrated at the physical layer, enabling quantum-safe data transmission through challenging subsea acoustic channels.
ML-KEM + AES-256 hybrid encryption for the entire sonar-to-combat system data chain, ensuring intercepted sonar intelligence remains secure against future quantum decryption.
Machine learning sonar target classification with a fully PQC-secured inference pipeline, delivering trusted underwater situational awareness with quantum-safe chain of custody for all classification outputs.
Submarine and underwater defense systems rely on encrypted communications channels and authenticated data links that use RSA, ECC, and Diffie-Hellman key exchange. Cryptographically relevant quantum computers will break every one of these algorithms, exposing the most sensitive undersea operations to adversarial exploitation.
Harvest-now-decrypt-later attacks are already capturing encrypted submarine communications and sonar data transmissions for future quantum decryption. Underwater acoustic networks, which carry critical tactical and strategic intelligence, face complete compromise once quantum computers mature.
