基于区块链的舰船通信数据防篡改模式研究

Research on tamper-proof mode of ship communication data based on block chain

现有舰船通信数据存储模式存在易被篡改等缺陷,结合具备防篡改特性的区块链技术设计通信数据防篡改模式,构建该模式中的舰船通信区块链结构,通过区块链共识机制由所构建的舰船通信区块链中选取最佳区块,以分层数字签名的方式向最佳区块内加密上传舰船通信数据,完成舰船通信数据的加密防篡改存储。结果表明,该模式在上传舰船通信数据过程中,可保持平稳的签名加密与最佳区块选取运算开销,并有效避免各类篡改攻击,具有较高的防篡改性能。最终存储的数组舰船通信数据中,最高被篡改与缺失数据量的占比仅为0.004%与0.02%,存储数据的整体安全性与完整性较为理想,可为舰船通信数据的安全存储提供保障。

Data storage model based on the analysis of the existing ship that communication is vulnerable to tampering with defects,such as the characteristic of combining with tamper-proof block chain tamper-proof technology design communication data model,built the model of ship communication block chain structure,through the chain block consensus mechanism by building a ship communicationsin the chain to select the best the block,To the best in the form of hierarchical digital signature block encryption communication data upload ships,in complete ship communication data encryption tamperproof storage,the results show that the model in the process of communication data upload ships,can keep the stable signature encryption and best block selection operation costs,and effectively avoid all kinds of tampering attacks,has high tamper-proof performance,In the array ship communication data stored in the end,the highest amount of tampered and missing data accounts for only 0.004%and 0.02%.The overall security and integrity of stored data is relatively ideal,which can provide a guarantee for the safe storage of ship communication data.
