摘要
针对现有身份凭证协议缺乏问责机制的问题,本文提出了一种具有问责机制的阈值签发身份凭证协议.该协议通过引入追踪者和动态累加器,实现对违规用户真实身份的追踪及其身份凭证的撤销.为了避免单点故障和问责权滥用,该协议将问责权分配给多个追踪者实体.与现有身份凭证协议对比分析以及在以太坊平台部署本文协议的智能合约并估算运行成本,结果表明,本文协议在保证问责功能的同时,还兼顾了效率、安全性和可行性.本文协议为基于区块链的身份凭证协议提供了一种具有实践价值的新方案.
Abstract
In view of the lack of an accountability mechanism in the existing threshold issuance identity credential protocols,this paper proposes a threshold issuance identity credential protocol with an accountability mechanism.The protocol introduces tracers and dynamic accumulators to track the real identity of the malicious user and revoke user's identity credentials.At the same time,in order to effectively avoid single point failures and abuse of accountability rights,the protocol distributes accountability rights to multiple tracker entities.By comparing and analyzing the experimental results of existing identity credential protocols,as well as deploying the smart contracts of the protocol on the Ethereum platform and estimating the operation cost,it is verified that the protocol maintains the accountability function while taking into account the efficiency,security,and feasibility.The proposed protocol provides a new solution with practical value for blockchain-based identity credential protocols.
