一句话总结

本文提出dNAS，一种基于企业区块链协议的去中心化NFC增强型防伪系统，旨在提升葡萄酒产业供应链的可追溯性与真实性。通过采用许可共识机制、智能合约以及IPFS实现不可篡改的数据存储，dNAS实现了对供应链各节点葡萄酒记录的密码学验证、端到端可追溯性，相较于集中式系统展现出更优的抗攻击能力与可信度。

ABSTRACT

A variety of innovative software solutions, addressing product anti-counterfeiting and record provenance of the wider supply chain industry, have been implemented. However, these solutions have been developed with centralized system architecture which could be susceptible to malicious modifications on states of product records and various potential security attacks leading to system failure and downtime. Blockchain technology has been enabling decentralized trust with a network of distributed peer nodes to maintain consistent shared states via a decentralized consensus reached, with which an idea of developing decentralized and reliable solutions has been basing on. A Decentralized NFC-Enabled Anti-Counterfeiting System (dNAS) was therefore proposed and developed, decentralizing a legacy anti-counterfeiting system of supply chain industry utilizing enterprise blockchain protocols and enterprise consortium, to facilitate trustworthy data provenance retrieval, verification and management, as well as strengthening capability of product anti-counterfeiting and traceability in supply chain industry. The adoption of enterprise blockchain protocols and implementations has been surging in supply chain industry given its advantages in scalability, governance and compatibility with existing supply chain systems and networks, but development and adoption of decentralized solutions could also impose additional implications to supply chain integrity, in terms of security, privacy and confidentiality. In this research, an empirical analysis performed against decentralized solutions, including dNAS, summarizes the effectiveness, limitations and future opportunities of developing decentralized solutions built around existing enterprise blockchain protocols and implementations for supply chain anti-counterfeiting and traceability.

研究动机与目标

• 为应对全球供应链中日益严峻的假冒产品威胁，特别是在集中式系统易受篡改与单点故障影响的葡萄酒产业中，提出解决方案。
• 评估去中心化防伪与可追溯性方案（特别是dNAS）在安全性、完整性与抗毁性方面是否优于集中式方案。
• 识别去中心化区块链系统在供应链管理中部署的集成挑战、局限性及未来机遇。
• 通过定性与定量测试，验证dNAS相较于其集中式前身的有效性。
• 探索未来在更广泛供应链领域部署中，提升安全性、隐私保护与可扩展性的优化方向。

提出的方法

• 在许可联盟模型下，采用企业区块链协议（如PoA、Quorum）设计并实现dNAS，以在去中心化、可扩展性与治理之间取得平衡。
• 在EVM兼容区块链上集成智能合约，以自动化并强制执行供应链各节点葡萄酒记录的状态转换。
• 使用IPFS（星际文件系统）实现大规模产品数据与链接到链上记录的数字孪生的去中心化、持久化存储。
• 对所有节点与交易应用密码学认证与验证机制，确保数据完整性并防止未授权修改。
• 采用混合系统集成模型，支持多样化利益相关方（如酿酒商、经销商、零售商），促进整个供应链的采纳。
• 实施隐私保护技术，如隐身地址、环签名以及可信执行环境（如Intel SGX），以增强数据机密性与密钥安全性。

实验结果

研究问题

• RQ1 去中心化的防伪与可追溯性方案（如dNAS）是否在对抗假冒产品攻击方面比集中式方案更有效且值得部署？
• RQ2 哪些集成模式与用户友好机制能够促进供应链参与者、终端消费者及行业利益相关方的采纳？
• RQ3 dNAS在安全性、性能与可靠性方面，与集中式系统相比在定性与定量层面表现如何？
• RQ4 dNAS部署中的关键局限性、风险与隐私担忧为何？未来可采取哪些改进措施？

主要发现

• dNAS成功满足所有既定系统需求，功能与性能测试均证实其宣称能力。
• 系统通过密码学验证的状态转换、联盟节点共识及区块链持久化，实现了葡萄酒记录的端到端可追溯性与不可篡改性。
• dNAS消除了单点故障与单点控制，显著提升了系统抗毁性与可用性，优于集中式系统。
• 去中心化架构确保任何单一实体均无法在无共识情况下修改记录，为每条葡萄酒记录提供可验证的存在性与所有权证明。
• 尽管可扩展性低于集中式系统，dNAS因去中心化与密码学强制机制，展现出更优的可信度、安全性与可审计性。
• 未来改进方向包括密钥轮换、零知识证明以及数字资产代币化，以进一步提升隐私保护、安全性，并增强与DeFi及电子商务生态系统的互操作性。
