摘　　要：随着跨境电商行业的飞速发展,跨境电商的相关数据呈爆炸性增长,数据安全问题日益凸显。传统的跨境电商平台通常面临着数据泄露、篡改和不可信的问题,导致商家和用户对平台的信任度下降。为了解决这一问题,本文提出一种基于零信任和区块链的跨境电商数据安全共享模型(EDSM-BZT)。首先,设计基于零信任的多因素身份认证方案,结合时间因素和知识因素对每一个访问主体进行动态验证。其次,在方案中加入信任评估策略,计算访问主体的信任值,对用户访问行为实现更细粒度控制。最后,在模型中构建链上链下协同存储子模型,确保跨境电商数据的安全传输和存储。实验结果表明,该模型可以实现访问授权的动态控制和跨境电商数据的高效存储,具有良好的性能和可扩展性。With the rapid development of cross-border e-commerce industry,the explosive growth of related data in crossborder e-commerce has made data security issues increasingly prominent.Traditional cross-border e-commerce platforms often face issues of data leakage,tampering,and untrustworthiness,leading to a decrease in the trust of merchants and users to the platform.To address this issue,this paper proposes a cross-border e-commerce data security sharing model based on zero trust and blockchain(EDSM-BZT).Firstly,a zero trust based multi factor identity authentication scheme is designed,which combines time and knowledge factors to dynamically verify each visitor.Secondly,a trust evaluation strategy is added to the scheme to calculate the trust value of the accessing subject and achieve more fine-grained control over user access behavior.Finally,an on chain and off chain collaborative storage sub model in the model is built to ensure the secure transmission and storage of crossborder e-commerce data.The experimental results show that the model can achieve dynamic control of access authorization and efficient storage of cross-border e-commerce data,with good performance and scalability.
