本文提出SPARTA系统,利用可信执行环境实现决策过程的自动化,通过加密技术保障隐私、完整性和可用性,同时支持定制、验证和安全性。

摘要:

决策支持系统正被越来越多地用于自动化各行业、组织和政府的决策过程。决策支持要求数据隐私、完整性和可用性,同时确保决策过程的定制、安全性和可验证性。现有解决方案无法保证这些属性。为克服这一限制,我们提出了SPARTA,一种基于可信执行环境(TEEs)的方法,自动化决策过程。为保证隐私、完整性和可用性,SPARTA在经过公证的数据上使用高效的加密技术,并通过用户定义的访问策略进行访问控制。我们的解决方案允许用户定义决策规则,这些规则被转换为经过认证的软件对象,部署在TEEs中,从而确保过程的定制性、可验证性和安全性。通过在公开基准和合成数据上进行实验,我们展示了我们的方法在可扩展性和开销方面优于非加密解决方案。

英文摘要:

Decision support systems are increasingly adopted to automate decision-making processes across industries, organizations, and governments. Decision support demands data privacy, integrity, and availability while ensuring customization, security, and verifiability of the decision process. Existing solutions fail to guarantee those properties altogether. To overcome this limitation, we propose SPARTA, an approach based on Trusted Execution Environments (TEEs) that automates decision processes. To guarantee privacy, integrity, and availability, SPARTA employs efficient cryptographic techniques on notarized data with access mediated through user-defined access policies. Our solution allows users to define decision rules, which are translated to certified software objects deployed within TEEs, thereby guaranteeing customization, verifiability, and security of the process. With experiments run on public benchmarks and synthetic data, we show our approach is scalable and adds limited overhead compared to non-cryptographically secured solutions.
