摘　　要：传统大数据共享安全认证方法经常出现错误问题,影响舰船航行大数据共享效率。为此,提出基于区块链的舰船航行大数据共享安全认证研究。根据舰船航行大数据的种类,计算出舰船航行大数据共享的总直接信任度,利用区块链技术对舰船航行大数据预处理,得到舰船航行大数据块标签,利用区块链技术确定每一个大数据子块的哈希值,判断舰船航行大数据共享的完整性,实现舰船航行大数据共享的安全认证。实验结果表明,所提方法在舰船航行大数据共享的安全认证中具有更高的可靠性和鲁棒性,从而提高了舰船航行大数据共享效率。The traditional big data sharing security authentication method often has errors,which affects the ship navigation big data sharing efficiency.To this end,the blockchain-based ship navigation big data sharing security certification research is proposed.The attenuating effect of computation time on direct trust.According to the types of ship navigation big data,the total direct trust of ship navigation big data sharing is calculated.The ship navigation big data is preprocessed with the blockchain technology to get the ship navigation big data block label,and the hash value of each big data sub-block is determined with the blockchain technology to judge the integrity of the ship navigation big data sharing and realize the security certification of the ship navigation big data sharing.The experimental results show that the proposed method has higher reliability and robustness in the safety certification of ship navigation big data sharing,thus improving the efficiency of ship navigation big data sharing.
