摘　　要：区块链的不可篡改性为产品供应链溯源提供了新的解决方案。然而,由于区块链的公开透明特性,供应链上的制造商、零售商等参与者的身份信息和共享的产品信息极易被伪造。对此,文章基于零知识证明技术设计了一种安全可信的产品信息共享方法,利用属性加密技术对存储在区块链中的产品信息进行了加密,并通过智能合约为产品信息密文设置了灵活的访问控制策略。模型评估结果显示,该方案可以很好地保护溯源系统中参与者的身份信息和产品的共享信息。The immutability of blockchain provides a new solution for product supply chain traceability.However,due to the open and transparent nature of blockchain,the identity information and shared product information of manufacturers,retailers,and other participants in the supply chain are easily forged.In this regard,this article designs a secure and trustworthy product information sharing method based on zero knowledge proof technology.It uses attribute encryption technology to encrypt product information stored in the blockchain,and sets flexible access control policies for product information ciphertext through smart contracts.The model evaluation results show that this scheme can effectively protect the identity information of participants and the shared information of products in the traceability system.
