摘　　要：近年来,为有效解决身份凭证出示的过程中存在的用户隐私信息泄露问题,学者们提出了匿名凭证系统。然而,传统匿名凭证容易提供过多非必要隐私信息,造成隐私泄露的风险。因此结合基于属性的签名,学者们提出了基于属性的匿名凭证。本文首先根据匿名凭证系统特性,将系统具体分为凭证颁发与凭证证明两个过程分别研究。其次,本文对每个过程所使用的算法结合现状研究并对比分析,根据具体结果针对不同使用情形提出建议,使得效果最优化。接着,综合分析几类具体的匿名凭证方案特性,进一步对比不同算法对凭证系统性能的影响。最后,对目前基于属性的匿名凭证已有研究提出所存在问题,并基于此对未来研究提出展望。In recent years,scholars proposed the anonymous credential system to solve the user privacy information leakage problem when presenting the identity credential.However,the traditional anony⁃mous credential is prone to provide overmuch unessential private information,leading to the privacy leakage risk.Thus,combined with the attribute⁃based signature,scholars proposed the attribute⁃based anonymous credential.In this paper,according to the characteristics of the anonymous credential sys⁃tem,the system is specifically divided into two processes of credential issuance and credential proof,which are studied separately.Then,algorithms used in each process are combined with the status quo research and the comparative analysis,and suggestions for different application scenarios are presented to optimize the system performance.In addition,characteristics of several specific anonymous credential schemes are comprehensively analyzed,and the impacts of different algorithms on the credential system performance are also compared.Finally,some issues occurring in existing attribute⁃based anonymous credentials research are presented and future research is prospected.
