Blockchain-Based Data Secure and Traceable Scheme for Industrial Internet of Things
Fei Yin, Chengliangyi Xia · 2023
Data security has become an important guarantee for the operation of Industrial Internet of Things (IIoT). Once the data is leaked or trampered with, it may cause economic losses and property security. In this paper, we propose a blockchain-based data secure and traceable scheme for IIoT. Specifically, we protect users' personal information and transmitted data by public-key cryptosystem with a double trapdoor decryption mechanism. In addition, the traceability of data and user information is realized through blockchain technology. Finally, the performance analysis on the Hyperledge Fabric platform shows that the scheme achieves privacy protection, traceability, reliability and authenticity, high computational and communication efficiency and low latency.
