基于可信计算的供应链金融系统
摘   要：在供应链金融项目实施过程中，逐步暴露出信息不对称、交易风险高、交易效率低等问题，通过多中心化的分布式结构实现了信息同步与共享，通过链式共享账本解决数据追溯与信息防伪，通过智能合约的编程特性规范业务交易。系统为可信计算技术提供安全可靠的区块链基础环境，实现了敏感数据在被保护的情况下，与业务系统保持连线、在专用硬件模块中自动地进行敏感数据的解密和处理、完全在加密硬件模块中进行数据处理，内鬼级的防护标准和无需额外配备敏感数据的存储设备以及维护人员。

Abstract： During the implementation of the supply chain finance project， the problems of information asymmetry， high transaction risk and low transaction efficiency are gradually exposed. Information synchronization and sharing are realized through the multi-center distributed structure. Data traceability and information anti-counterfeiting are solved through the chain Shared ledger. System as the trusted computing technology based environment， provide safe and reliable chain block implements the sensitive data in the case of protected， keep in connection with the business system and automation in the dedicated hardware module declassification of sensitive data and processing， completely for data processing in the hardware encryption module， ghost level protection standards and no additional with sensitive data storage devices and maintenance personnel.

1 引言
區块链和分布式账本技术是目前全球十大战略技术趋势之一，在国内外金融界、科技界受到高度关注。在国外，诸如R3、Hyperledger等各类机构纷纷成立，同时国内的各大科技巨头也争先抢占区块链领域。
现阶段，供应链金融是我国区块链技术应用最为广泛的领域，技术相对成熟，规模不断扩大。供应链金融可信区块链系统是指利用加密算法、电子签名、智能合约等多项技术的融合，实现区块链上数据安全可信，确保供应链多方建立“技
