Co-communication Protocol of Underwater Sensor Networks with Quantum and Acoustic Communication Capabilities

The concept of communication using acoustic media of underwater sensor networks is important in pollution monitoring, oceanographic data collection and meet future development needs. To improve communication security, it is proposed co-communication of underwater sensor networks with quantum and acoustic communication capabilities by taking advantage of quantum communication and entanglement correlation nonlocality. Between the surface base station and autonomous underwater vehicle, it shares quantum keys by quantum communication and classical communication. Between autonomous underwater vehicle and underwater nodes, it employs symmetric cryptography without causing much encryption and decryption overhead to relay information and correct received information with low-complex on current technique level. In addition, it particularly analyzes the security and throughput efficiency.
