High fidelity encryption transmission method based on underwater acoustic sensor
A high fidelity encryption transmission method for underwater acoustic sensor is proposed.Aiming at disadvantage that the processor needed by software encryption on the ocean is relatively complex and encryption speed is slow,which can not meet the practical application requirements of information real-time and miniaturization,this paper focuses on the research from fusion,encryption and coding of target information.Reliable and safe wireless digital transmission of target information at sea can be achieved with high precision underwater acoustic detection module and high speed digital processor of FPGA and combined with RSA digital encryption algorithm.Finally,display on data terminal interface and simulation experiment is carried out.Test results show that the method collects the orthogonal vector underwater acoustic signal and boost underwater acoustic signal with zero time difference,and synchronously and wirelessly transmit to the host computer by cluster encryption together with magnetic signals,which can achieve high precision and high fidelity target information restoration.
