供应链金融为信贷额度低、融资规模小的中小企业提供信贷。由此产生的金融信用数据和相关业务交易数据是高度机密和私有的。然而，传统的SCF管理方案采用第三方平台和集中式设计，无法实现高可靠的安全存储和细粒度的访问控制。为了满足这一需求，我们提出了Fabric-SCF，通过利用分布式共识来设计和实现基于区块链的安全存储系统，以实现数据的安全性、可追溯性和不可变性。采用基于属性的访问控制模型进行访问控制，并利用智能合约定义系统流程和访问策略，保证系统高效运行。为了验证Fabric-SCF的性能，设计了两组仿真实验。实验结果表明，Fabric-SCF在模拟真实操作场景中实现了动态和细粒度的访问控制，同时保持了高吞吐量。
Supply chain finance (SCF) provides credit for small and medium-sized enterprises with low credit lines and small financing scales. The resulting financial credit data and related business transaction data are highly confidential and private. However, traditional SCF management schemes use third-party platforms and centralized designs that cannot achieve highly reliable secure storage and fine-grained access control. To address such a need, we propose Fabric-SCF, designing and implementing a Blockchain-based secure storage system by utilizing distributed consensus to realize data security, traceability, and immutability. The attribute-based access control model is deployed for access control, also utilizing smart contracts to define system processes and access policies to ensure the system's efficient operation. To verify the performance of Fabric-SCF, two sets of simulation experiments are designed its effectiveness. Experimental results show that Fabric-SCF achieves dynamic and fine-grained access control while maintaining high throughput in a simulated real-world operating scenario.
