摘要

元宇宙作为虚实融生的三元世界，为人们提供了海量多样化的网络服务，但由于缺乏现实世界的面对面交流且无法打破地理与时间的限制，现有方案无法在高效认证数字公民的同时实现隐私保护与监管。基于此，提出一种面向元宇宙的数字公民身份认证方案。依据身份时效性设计分层认证方案，基于 Paillier 同态加密和保持结构性签名等算法实现去中心化标识符与可验证凭证的双重不可链接，并借助代码嵌入技术保障公民的被遗忘权，保护公民隐私；而且在认证过程中嵌入监管因子，以供日后追责。最后，安全性分析证明了所提方案满足不可链接性、可追溯性；性能分析表明了所提方案具有较低计算成本和Gas开销，可满足实际应用需求。

Abstract

As a surreal ternary world

the metaverse provides people with massive and diverse network services.However

due to the lack of face-to-face communication in reality and the broken geographical and time constraints

the existing schemes cannot effectively authenticate digital citizens while realizing privacy protection and accountability.Therefore

a metaverse-oriented digital citizen authentication scheme was proposed.Firstly

a layered authentication scheme based on the time-sensitive identity was constructed.Secondly

for protecting citizens’ privacy

the Paillier homomorphic encryption algorithm and structure-preserving signature scheme were introduced to realize the double unlink ability of decentralized identifiers and verifiable credentials

in addition

the citizens’ right to be forgotten was guaranteed by the code embedding technology.Thirdly

the regulatory factor during the authentication phase for accountability was designed.Finally

the security analysis proves that the proposed scheme satisfies the unlinkability and traceability.And

the performance analysis shows that the proposed scheme has lower computational cost and gas overhead

which can meet the needs of practical use.
