摘　　要：工业互联网是未来工业发展的主流趋势,其中供应链是工业互联网中十分重要的一环。在传统的供应链中,维护可追溯性和所有权仍然是一个严重的问题。利用区块链可以增加信任,提高可追溯性,而无需第三方机构进行信任背书的特性,可以提高供应链系统的管理效率和性能。然而,区块链技术在保证供应链数据透明的同时,也引发了交易隐私泄露问题。基于此,提出一种考虑所有权和可追溯性的交易隐私保护方法,该方法保留了区块链和集中式数据库服务器的优点,通过生成对称密钥、使用产品代码和时间戳来实现隐私保护。The industrial Internet is the mainstream trend of future industrial development,and the supply chain is a very important part of the industrial Internet.In traditional supply chains,maintaining traceability and ownership remains a serious issue.The use of blockchain can increase trust and improve traceability taht without the need for third-party institutions to endorse trust features,which can improve the management efficiency and performance of the supply chain system.However,while blockchain technology ensures the transparency of supply chain data,it also raises the issue of transaction privacy disclosure.Based on this,this paper proposes an approach to transaction privacy protection that considers ownership and traceability,which preserves the advantages of blockchain and centralized database servers,and achieves privacy protection by generating symmetric keys,using product codes and timestamps.
