Design of Blockchain-Based Real-time 3D Geographic Information Data Encryption Control System
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 pro-cessing 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 cryptogra-phy,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.Combi-ning the relevant hardware application structure,complete the design of blockchain-based realistic 3D geographic information data en-cryption 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 in-formation data.
