细粒度的仪表读数支持高级计量基础设施中的应用。然而，这些水表读数暗示了家庭日常活动的草图，从而威胁到个人隐私。在智能计量系统中，隐私问题已经通过可信第三方假设或加密原语来解决。我们使用一个可信的平台模块和轻量级的加密原语来解决隐私问题。我们的智能计量系统以隐私保护的方式同时支持计费和负载监控应用。它允许电力服务提供商获得在一段时间内的仪表读数的总和，并且允许监控中心在某个最近的时间单位从区域中的仪表获得仪表读数的总和，同时保持单独的仪表阅读私密。此外，我们正式证明，我们的系统是隐私保护。我们的系统提供了一个简单但非常实用的解决方案，隐私保护智能计量系统。
Fine-grained meter readings enable applications in an advanced metering infrastructure. However, those meter readings threaten personal privacy by implying a sketch of daily activities of households. The privacy issue has been addressed in smart metering systems by either a trusted third party assumption or cryptographic primitives. We address the privacy issue by using a trusted platform module and lightweight cryptographic primitives. Our smart metering system simultaneously supports the billing and load monitoring applications in a privacy preserving manner. It allows an electricity service provider obtain sums of meter readings over a time period and a monitoring center obtain sums of meter readings from meters in an area at some recent time unit while keeping individual meter reading private. Moreover, we formally prove that our system is privacy preserving. Our system provides a simple yet very practical solution to a privacy preserving smart metering system.
