摘要:
区块链技术的快速发展推动了去中心化账户管理的广泛应用,尤其在数字资产和身份管理方面,然而,传统的私钥管理模式存在着私钥丢失或泄露风险,用户一旦丢失私钥便永久失去对资产的控制权。 近年来,智能合约抽象账户已成为一种新型的去中心化数字身份管理方式,不仅提高了用户数据的隐私保护,还允许用户自主掌控身份信息,提供了去信任、不可篡改的身份验证手段。 智能合约账户通过智能合约与用户身份绑定,能够自动化执行身份验证和资产管理任务,赋予用户对数字资产的自主控制权。 现有的许多方案使用安全多方计算技术将私钥分割成多个片段分布存储,防止了单点故障,且仅在满足一定数量的参与方协作时才能重建私钥。 这种方法提高了安全性,但在实际应用中,当门限无法达成时,私钥恢复往往面临失败的风险。 为了解决这个问题,文中方案结合多方计算技术和基于域名识别邮件协议的社交恢复,通过引入邮件验证和零知识证明为私钥恢复提供了备用路径。 这样,即使门限条件无法满足,用户也可以通过安全的社交恢复方式重获对合约账户的访问权。 该方案提高了私钥管理的灵活性和安全性,为区块链生态中的数字资产管理提供了新的思路。
Abstract:
The rapid development of blockchain technology has promoted the widespread adoption of decentralized account management,particularly in digital asset and identity management. However,traditional private key management methods come with the risk of key loss or exposure,whereby users lose permanent control over their assets if they lose their private keys. Recently,smart contract-based abstract accounts have emerged as a new decentralized digital identity management approach. This approach not only enhances user data privacy protection but also allows users to control their identity information autonomously,providing a trustless and tamper-proof method for identity verification. Smart contract accounts bind user identities through smart contracts,enabling the automated execution of identity verification and asset management tasks and granting users autonomous control over their digital assets. Many existing solutions leverage secure multi-party computation (MPC) technology to split the private key into multiple fragments stored across various locations,thereby preventing single points of failure. Only when a certain number of participants collaborate can the private key be reconstructed. Although this method enhances security,in practical applications,private key recovery can fail when the required threshold cannot be reached. To address this issue,the proposed solution combines MPC technology with a DomainKeys Identified Mail (DKIM) for social recovery,in-troducing email verification and zero-knowledge proof as a fallback mechanism for private key recovery. This way,even if the threshold condition is not met,users can regain access to their contract accounts through secure social recovery. The proposed approach enhances both the flexibility and security of private key management,offering new avenues for digital asset management within the blockchain eco-system.
