在本文中,我们描述了在 NSF 资助的项目 ImPACT(隐私保证计算基础设施)过程中开发和原型化的架构。该架构解决了在多机构、多利益相关者环境中安全存储、控制访问和处理隐私受限数据的需要而产生的常见问题。具体来说,该架构包括几个组件——一种在不暴露敏感数据本身的情况下公开宣传一组有限数据属性的方法;数据所有者指定并自动执行复杂数据访问策略的一组机制,目前通常表示为 DUA(数据使用协议);一种安全地从多个利益相关者收集数字证明以满足这些政策的方法;以及用于部署安全处理飞地的可复制模板,研究人员可以在其中使用他们选择的工具以符合数据所有者策略的方式分析数据。本文描述了该架构及其在原型中的实例化,提供了多个组件的性能评估。
In this paper we describe an architecture developed and prototyped in the course of the NSF-funded project called ImPACT—Infrastructure for Privacy-Assured CompuTations. This architecture addresses the common problems that arise from the need to securely store, control access to and process privacy-restricted data in a multi-institutional, multi-stakeholder setting. Specifically the architecture includes several components—a way to publicly advertise a limited set of data attributes without exposing the sensitive data itself; a set of mechanisms for a data owner to specify and automatically enforce complex data-access policies commonly expressed today as DUAs (Data Use Agreements); a way to securely collect digital attestations from multiple stakeholders to satisfy those policies; and a reproducible template to deploy secure processing enclaves in which groups of researchers can analyze the data in a way that complies with data owner policies using the tools of their choice. The paper describes the architecture and its instantiation in a prototype, providing a performance evaluation of several components.
