摘要
研究基于区块链技术的船舶信息安全预测方法,提升船舶信息传输的安全性。利用模型链整合区块链技术与信息安全预测算法,实现船舶信息的安全传输。模型链选取Boosting算法作为信息安全预测算法,预测船舶信息传输节点的决策权。确定具有决策权的船舶信息传输节点后,区块链技术采用改进的共识机制,利用区块链加密服务提供商为船舶信息传输提供密码服务。区块链加密服务提供商选取SM2签名算法作为区块链加密服务的数字签名方案,保证船舶信息传输安全。实验结果表明,船舶通信系统节点数量为80个时,区块链技术的共识效率提升比高达22%,可以实现船舶信息的安全传输。
Research on the ship information security prediction method based on blockchain technology to improve the security of ship information transmission.The model chain is used to integrate blockchain technology and information security prediction algorithms to realize the secure transmission of ship information.The model chain selects the Boosting algorithm as the information security prediction algorithm to predict the decision-making power of the ship information transmission node.After determining the ship information transmission node with decision-making power,the blockchain technology adopts an improved consensus mechanism,and uses the blockchain encryption service provider to provide encryption services for ship information transmission.The blockchain encryption service provider selects the SM2 signature algorithm as the digital signature scheme for the blockchain encryption service to ensure the security of ship information transmission.The experimental results show that when the number of nodes in the ship communication system is 80,the consensus efficiency improvement ratio of blockchain technology is as high as 22%,which can realize the safe transmission of ship information.
