摘要:

在本文中,我们提出了GraphSE $^2$,一个加密的图形数据库,用于在线社交网络服务,以解决大规模的数据泄露。GraphSE $^2$保留了社交搜索的功能,这是高质量社交网络服务的关键推动因素,其中社交搜索查询在大规模社交图上进行,同时对用户生成的内容执行集合和计算操作。为了实现高效的隐私保护社交搜索,GraphSE $^2$提供了一个加密的结构化数据模型,以促进并行和加密的图形数据访问。它还旨在将复杂的社交搜索查询分解为原子操作,并通过可互换的协议以快速和可扩展的方式实现它们。我们使用Facebook图搜索引擎中支持的各种查询构建GraphSE $^2$,并实现了一个成熟的原型。对Azure Cloud的广泛评估表明,GraphSE $^2$对于查询具有百万用户的社交图是实用的。

英文摘要:

In this paper, we propose GraphSE$^2$, an encrypted graph database for online social network services to address massive data breaches. GraphSE$^2$ preserves the functionality of social search, a key enabler for quality social network services, where social search queries are conducted on a large-scale social graph and meanwhile perform set and computational operations on user-generated contents. To enable efficient privacy-preserving social search, GraphSE$^2$ provides an encrypted structural data model to facilitate parallel and encrypted graph data access. It is also designed to decompose complex social search queries into atomic operations and realise them via interchangeable protocols in a fast and scalable manner. We build GraphSE$^2$ with various queries supported in the Facebook graph search engine and implement a full-fledged prototype. Extensive evaluations on Azure Cloud demonstrate that GraphSE$^2$ is practical for querying a social graph with a million of users.
