摘要
针对工业互联网数据溯源过程中存在的不安全问题,提出一种基于区块链的工业互联网数据溯源方案。利用射频识别技术中的阅读器对工业产品生产、加工、仓储、运输和销售全过程进行信息采集,并存储于电子标签中转为二维码方便溯源。同时,通过对称加密算法对工业产品的隐私信息进行加密,采用公钥加密算法加密对称密钥后存储于区块链中,调用智能合约实现信息存储和共享。安全性分析和性能分析表明,该方案可提高工业产品信息安全性、溯源过程可靠性和数据传输高效性。
Aiming at the insecurity problems in the process of industrial Internet data traceability,a blockchain-based industrial Internet data traceability scheme is proposed.The reader in radio frequency identification technology is used to collect information in the whole process of production,processing,warehousing,transportation and sales of industrial products,and store it in the electronic label and convert it into a quick response(QR)code,which is convenient to trace the source.At the same time,the private information of industrial products is encrypted by symmetric encryption algorithm,and the symmetric key is encrypted by public key encryption algorithm and stored in the blockchain,and smart contracts are called to realize information storage and sharing.Security analysis and performance analysis show that this scheme can improve the information security of industrial products,the reliability of traceability process and data transfer efficiency.
