摘　　要：为解决由公钥文本、私钥文本不匹配造成的信息数据错误加密问题,实现对实景三维地理信息数据的按需加密处理,设计了基于区块链的实景三维地理信息数据加密控制系统;设置CPU主机端调度模块、地理信息数据处理模块和混合加密模块作为主要元件,联合数字签名结构,完善矢量化计算单元的连接形式,完成对数据加密控制系统硬件的设计;按照区块链编码原则,确定关键区块角色的组成情况与公钥密码体制定义条件,并以此为基础,计算数据多项式结果;再根据Curl加密节点部署形式,求解隐藏加密向量的具体数值,实现对实景三维地理信息数据的加密处理;结合相关硬件应用结构,完成基于区块链的实景三维地理信息数据加密控制系统的设计;实验结果表明,设计系统的公钥文本、私钥文本之间的长度差不超过0.25 kB,能够较好解决由密钥文本不匹配造成的信息数据错误加密问题,符合按需加密处理实景三维地理信息数据的实际应用需求。To solve the incorrect encryption of information data caused by mismatch between public key text and private key text,and to achieve the on-demand encryption processing of real 3D geographic information data,a realistic 3D geographic information data encryption control system based on blockchain was designed.Set the CPU host scheduling module,geographic information data processing module,and hybrid encryption module as the main components,combine digital signature structure,improve the connection form of vectorizing the calculation unit,and complete the hardware design of the data encryption control system.According to the principles of blockchain encoding,determine the composition of key block roles and the definition conditions of public key cryptography,and based on this,calculate the data polynomial results.Based on the deployment form of Curl encryption nodes,the specific values of hidden encryption vectors are solved to achieve the encryption processing of realistic 3D geographic information data.Combining the relevant hardware application structure,complete the design of blockchain-based realistic 3D geographic information data encryption control system.The experimental results show that the length difference between the public key text and private key text of the designed system does not exceed 0.25KB,which can effectively solve the incorrect encryption of information data caused by the key text mismatch,and meets the practical application requirements of on-demand encryption processing of realistic 3D geographic information data.
