With the increase in the market share of data trading, the risks such as identity authentication and authority management are increasingly intensified. Aiming at the problems of centralization of identity authentication, dynamic changes of identities, and ambiguity of trading authority in data trading, a two-factor dynamic identity authentication scheme for data trading based on alliance chain (BTDA) is proposed. Firstly, the use of identity certificates is simplified to solve the problems of large calculation and difficult storage. Secondly, a two-factor dynamic authentication strategy is designed, which uses distributed ledger to achieve dynamic identity authentication throughout the data trading. Finally, a simulation experiment is carried out on the proposed scheme. The theoretical comparison and analysis with similar schemes show that the proposed scheme has lower cost, higher authentication efficiency and security, easier authority management, and can be widely used in various fields of data trading scenarios.
随着数据交易市场份额的增加，身份认证和权限管理等风险日益加剧。针对数据交易中身份认证集中化、身份动态变化以及交易权限模糊等问题，提出了一种基于联盟链的数据交易双因素动态身份认证方案（BTDA）。首先，简化身份证书的使用，解决计算量大和存储困难的问题。其次，设计了一种双因素动态认证策略，利用分布式账本在整个数据交易过程中实现动态身份认证。最后，对所提方案进行了仿真实验。与类似方案的理论比较和分析表明，所提方案成本更低、认证效率和安全性更高、权限管理更便捷，可广泛应用于数据交易场景的各个领域。
