XYZ隐私

XYZ Privacy

Josh Joy, Dylan Gray, Ciaran McGoldrick, Mario Gerla

摘要:

未来的自动驾驶汽车将作为新兴物联网场景中的关键网关设备生成、收集、聚合和消费大量数据。虽然车辆被广泛认为是实现有效数据通信的最具挑战性的移动环境之一,但对这些车辆产生的数据的隐私性关注较少。这种私有化数据的质量和可用性将成为未来安全高效交通解决方案的核心。在本文中,我们提出了XYZ隐私机制。据我们所知,XYZ隐私是第一个这样的机制,它使数据创建者能够对查询提交多个相互矛盾的响应,同时保留实际原始数据的绝对误差。这些功能以可扩展和安全的方式实现。例如,可以在保留实用性的同时混淆单个位置数据,从而使该方案能够透明地与现有系统(例如Waze)集成。一个新的加密原语功能秘密共享是用来实现非归属写,我们显示了一个数量级的改进,从默认的实现。

英文摘要:

Future autonomous vehicles will generate, collect, aggregate and consume significant volumes of data as key gateway devices in emerging Internet of Things scenarios. While vehicles are widely accepted as one of the most challenging mobility contexts in which to achieve effective data communications, less attention has been paid to the privacy of data emerging from these vehicles. The quality and usability of such privatized data will lie at the heart of future safe and efficient transportation solutions. In this paper, we present the XYZ Privacy mechanism. XYZ Privacy is to our knowledge the first such mechanism that enables data creators to submit multiple contradictory responses to a query, whilst preserving utility measured as the absolute error from the actual original data. The functionalities are achieved in both a scalable and secure fashion. For instance, individual location data can be obfuscated while preserving utility, thereby enabling the scheme to transparently integrate with existing systems (e.g. Waze). A new cryptographic primitive Function Secret Sharing is used to achieve non-attributable writes and we show an order of magnitude improvement from the default implementation.
