摘要
我们提出了集中属性收集服务(CACS),这是一种在云中存储凭证的系统,具有满足用户的隐私属性,并为依赖方提供额外的保证。该系统部署了隐私增强技术,以保护提交给依赖方的用户身份和凭据。同时,该系统可以保证发行者对依赖方的信任。该系统还允许用户获取其凭据的访问日志,使他们能够将其与使用情况进行比较。向依赖方提交证书遵循移动驾驶执照(mDL, ISO 18013-5)的标准协议。
CACS: A Cloud Privacy-Preserving Attribute Management System
We present Centralized Attribute Collection Service (CACS), a system for storing credentials in the cloud, with satisfying privacy properties for users, and additional assurances for relying parties. The system deploys privacy-enhancing technologies to protect users’ identities and credentials presented to relying parties. At the same time, the system can vouch for the trustfulness of issuers to relying parties. The system also allows users to obtain the access logs for their credentials, enabling them to compare them against their usage. The presentation of credentials to relying parties follows the standard protocols of Mobile Driving Licence (mDL, ISO 18013-5).
