摘要:

去中心化标识符已成为数字身份架构的标准化组成部分,欧盟等超国家组织将其作为统一欧洲数字身份账本的核心组件加以采用。本文深入研究通过整合环签名作为替代验证方法,来增强去中心化标识符的安全性与隐私特性。该方法允许用户通过数字签名完成身份验证,且不会泄露自己使用的是哪个公钥。为此,本研究提出了一种新颖的去中心化身份方法,并在一个基于去中心化标识符的架构框架中进行了展示。此外,本研究评估了在验证流程中采用该新方法的影响,重点聚焦于隐私与安全层面。尽管环签名已是密码协议中的成熟工具,本文仍试图在不断发展的数字身份领域挖掘其应用潜力。

英文摘要:

Decentralised identifiers have become a standardised element of digital identity architecture, with supra-national organisations such as the European Union adopting them as a key component for a unified European digital identity ledger. This paper delves into enhancing security and privacy features within decentralised identifiers by integrating ring signatures as an alternative verification method. This allows users to identify themselves through digital signatures without revealing which public key they used. To this end, the study proposed a novel decentralised identity method showcased in a decentralised identifier-based architectural framework. Additionally, the investigation assesses the repercussions of employing this new method in the verification process, focusing specifically on privacy and security aspects. Although ring signatures are an established asset of cryptographic protocols, this paper seeks to leverage their capabilities in the evolving domain of digital identities.
