摘要:	隨著近年來區塊鏈應用如雨後春筍般的大量發展，有許多人開始嘗試在去中心化的網路上，如區塊鏈網路，部署數位身份的管理系統，然而，因為在區塊鏈中的資料具有公開透明的特性，對於數位身份系統這類需要隱私保護的應用來說，存在著一些難題需要克服。為了解決此問題，我們採用模糊傳輸(oblivious transfer)與可信執行環境(trusted execution environment)來達成對使用者隱私的保護。此外，我們提出一個系統，此系統能夠將使用者的身份屬性從現存的伺服器，轉移至區塊鏈網路上，並且在智能合約中驗證屬性來源是否為可信任，根據驗證結果決定是否將使用者的屬性發行於區塊鏈網路上，同時保護屬性的隱私。在此系統的屬性驗證協定中，我們將可信執行環境使用在機密智能合約(confidential smart contract)中，藉此確保智能合約在執行驗證的邏輯運算時的隱私。同時，在此系統中，使用者可以自由地控制他們自己的屬性，也能將已驗證的屬性組成身份，來向服務提供商提交使用。此外，我們也採用智能合約來記錄屬性的當前狀態，透過改變記錄在智能合約上的屬性當前狀態，來達到批次撤銷身份的目的。我們也在此篇論文中提供本系統的安全性分析，以及與其他基於區塊鏈的身份系統的比較分析，藉此說明我們的系統在隱私保護、以使用者為中心的系統與撤銷機制上所具備的優勢。 With the rapid development of blockchain applications, digital identity management systems have started being deployed on decentralized networks. However, the inherent transparency of blockchain technology poses a challenge to privacy-conscious applications. To address this challenge, we adopt a DDH-based oblivious transfer and trust execution environment (TEE) to hide users’ private attributes. Furthermore, we propose a concrete system that includes transferring users’ attributes from a legacy server for verifying and issuing on the blockchain. In verifying protocol, we apply TEE in confidential smart contracts that execute the verification logic privately. Users can control their data and freely compose their identities using verified attributes. We also leverage smart contracts to record the status of attributes to achieve batch revocation of identities. Security analysis and comparison demonstrate that our system achieves privacy protection and is more user-centric in revocation than existing blockchain-based identity systems.
