摘　　要：为解决食用农产品溯源中存在的身份隐私易泄露、难监管以及溯源数据共享困难等问题,该文提出一种基于新型公平盲签名和属性基加密的食用农产品溯源方案。该方案在联盟链授权访问、不可篡改特性的基础上,结合椭圆曲线和零知识证明提出一种新型公平盲签名方法,实现了食用农产品数据上传者身份条件匿名并通过双重ID机制避免了签名方陷害问题;方案同时采用Asmuth-Bloom门限改进的属性基加密结合智能合约技术实现了权限分层的食用农产品溯源数据秘密共享。各项分析及实验结果表明,该方案具备良好的安全性和功能性。In order to solve the problems of identity privacy easy to leak,difficult to monitor and difficult to share the traceability data in the existing edible agricultural products traceability scheme,a traceability schema of edible agricultural products based on novel fair blind signature and attribute-based encryption is proposed.Based on the authorized access and non-tampering characteristics of consortium blockchain,a novel fair blind signature method is proposed by combining elliptic curve and zero-knowledge proof,which achieves anonymity of the identity of the edible agricultural product data uploader and avoids the problem of enmiting the signer through the double ID mechanism.At the same time,the attribute-based encryption improved by Asmuth-Bloom threshold combined with smart contract technology is adopted to realize the secret sharing of traceability data of edible agricultural products with hierarchical permissions.The analysis and experimental results demonstrate that the proposed scheme has good security and functionality.
