摘　　要：当前的船舶通信数据实时加密形式一般设定为单向加密结构,加密的综合覆盖范围较小,导致实时加密吞吐率较低,为此提出基于区块链技术的船舶通信数据实时加密方法。根据当前加密需求及标准的变动,首先生成船舶通信数据密钥,其次采用多目标的方式,扩大加密综合覆盖范围,再次设计多目标区块加密矩阵,构建区块链船舶数据实时加密模型,最后采用交互标定修正实行加密处理。测试结果表明,对比于传统Present通信数据实时加密测试组、传统机器学习数据实时加密测试组,本次所设计的区块链船舶通信数据实时加密测试组得出的吞吐率更高,说明在区块链技术的辅助下,所设计的数据实时加密方法应用效果更好,针对性更高,具有实际的应用价值。The current form of real-time encryption for ship communication data is generally set as a one-way encryption structure,with a small comprehensive coverage of encryption,resulting in low real-time encryption throughput.Therefore,a blockchain based real-time encryption method for ship communication data is proposed.Based on the current encryption requirements and changes in standards,the ship communication data key is first generated,followed by a multi-objective approach to expand the comprehensive coverage of encryption.The multi-objective block encryption matrix is designed again,and a real-time encryption model for blockchain ship data is constructed.Finally,cross calibration correction is used to implement encryption processing.The test results show that compared to the traditional Present communication data real-time encryption test group and the traditional machine learning data real-time encryption test group,the designed blockchain ship communication data real-time encryption test group has a higher throughput rate,indicating that with the assistance of blockchain technology,the designed data real-time encryption method has better application effect,higher specificity,and practical application value.
