摘　　要：针对现有集中式众包物流平台中用户身份数据存储与管理存在的隐私泄露和篡改问题,提出一种基于UTXO模型区块链的众包物流可信身份认证模型.该模型包括利用区块链技术实现身份注册、身份验证、身份撤销及身份认证.针对链上存储用户隐私数据风险的问题,采用混合加解密方案对链上个人信息做安全存储与分享;针对平台认证用户身份的问题,采用可信身份凭证以零知识证明方式登录众包物流平台.对身份信息以及认证进行安全性分析,并将该方法与LIU方法、LI方法的安全性能进行了对比.在Python3.9环境下完成试验,进行了身份信息加密和零知识身份认证测试分析.结果表明该方案的认证时延和处理事务能力均优于现有的SHAO方案.To solve the problems of privacy leakage and data tampering in the storage and management of user identity data on existing centralized crowdsourcing logistics platforms,the trusted identity authentication model based on the unspent transaction output(UTXO)model blockchain was proposed.The implementation of identity registration,identity verification,identity revocation and identity authentication was realized in the model by blockchain technology.To solve the risks associated with storing user privacy data on the blockchain,the hybrid encryption and decryption scheme was adopted to ensure the secure storage and sharing of personal information on the chain.For the issue of platform user identity authentication,the trusted identity credential was used to log into the crowdsourcing logistics platform by the zero-knowledge proof method.The security of identity information and authentication was analyzed,and the security performance of the proposed method was compared with those of the LIU and LI methods.The experiments were completed in Python 3.9 environment,and the identity information encryption and zero-knowledge identity authentication were tested and analyzed.The experimental results show that the authentication latency and transaction processing capability of the proposed scheme are superior to those of the existing SHAO scheme.
