SBIR Phase I: Blockchain for Supply Chain

小型企业创新研究(SBIR)第一阶段项目的更广泛影响/商业潜力是促进制成品更快、更安全的交易。当前的企业资源规划(ERP)解决方案基于相对较旧的技术。拟议的项目利用区块链技术为供应链开发了一个新的平台，以实现可扩展、安全和可互操作的解决方案。SBIR第一阶段项目解决了区块链商业解决方案的三个主要技术挑战，即可扩展性、安全性和互操作性。对于可伸缩性，核心技术要求是提供、维护和定期轮换用于签署交易并可由非技术用户使用的分层和确定性公钥/私钥对。安全研究将侧重于为每个组织/参与者提供向生态系统中的其他组织/参与者提供对现场级数据的精细访问的能力。该项目将使用椭圆曲线Diffie-Hellman(ECDH)协议来加密每个字段及其自己的密钥对。该系统将使用区块链智能合约，根据提交者设置的访问控制策略提供可信解密。该项目的互操作性将集中在不同区块链网络之间以及传统ERP系统和区块链网络之间共享数据的能力，方法是开发一种互操作性协议，安全地传输记录，并确保不可能发生双重支出类型的攻击。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to facilitate faster and safer transactions for manufactured goods. Current Enterprise Resource Planning (ERP) solutions are based on relatively old technology. The proposed project develops a new platform for the supply chain to operate efficiently using blockchain technology for a scalable, secure, and interoperable solution. The SBIR Phase I project addresses three principal technical challenges of a blockchain commercial solution, namely scalability, security and interoperability. For scalability, the core technical requirement is to provision, maintain and periodically rotate hierarchical and deterministic public/ private key-pairs used to sign transactions and usable by non-technical users. Security research will focus on providing each organization/ participant the ability to provide granular access to field-level data to others in the ecosystem. The project will use an Elliptic-Curve Diffie-Hellman (ECDH) protocol to encrypt each field with its own key-pair. The system will use a blockchain smart contract to provide trustable decryption based on access control policies set by the submitter. The project’s interoperability will focus on the ability to share data between different blockchain networks as well as between traditional ERP systems and a blockchain network by developing an interoperability protocol that securely transfers the record and ensures that double-spend type attacks are not possible.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
