以區塊鏈技術強化供應鏈產品履歷機制之研究

A Study of Strengthen Supply Chain Product Portfolio Mechanism Based on Blockchain Technology

近年全球市場的發展變化以及資訊網路的快速成長，傳統供應鏈企業的系統紀錄仍然採集中式儲存、缺乏透明度，故許多學者提出運用區塊鏈技術去中心化、防篡改且資訊公開透明等特性來改善現行供應鏈管理，然而當前基於區塊鏈的供應鏈管理系統在節點權限控制等方面有許多威脅及網路攻擊的安全隱憂。因此，本研究提出以區塊鏈技術強化供應鏈產品履歷機制之研究，將基於區塊鏈技術之特性結合智能合約設計產品履歷機制，並整合橢圓曲線密碼學技術之簽密法及自我認證機制，強化機制及數據之可驗證性及安全性；另依據區塊鏈技術特性分析預期可達到之安全性，並與相關學者研究方案實施比較，以驗證本研究方案之效益及可行性，期提升供應鏈整體企業效能。

With the recent changes in the global market and the rapid growth of information networks, system records of traditional supply chain enterprises are still stored centrally and lack transparency. Therefore, many scholars propose using blockchain technology to improve the current supply chain management (SCM) with decentralized, tamper-proof and transparent information. However, the current blockchain-based supply chain management system faces many threats in terms of node privilege control and security concerns regarding cyber-attacks. Therefore, this study proposes to strengthen the product history mechanism of supply chain by using blockchain technology, combining the characteristics of blockchain technology with smart contract to design the product history mechanism, and integrating signcryption using elliptic curve cryptography and self-authentication mechanism to strengthen the verifiability and security of the mechanism and data. In addition, we will analyze the security expected to be achieved based on the characteristics of blockchain technology and compare it with the implementation of the research proposal of related scholars to verify the effectiveness and feasibility of this research proposal and to improve the overall enterprise performance of the supply chain.
