论文摘要
近年来,关于智能计量的隐私研究,已经提出了许多建议。在一种考虑的方法之一中,称为匿名化,智能电表以能源供应商无法精确确定程序的方式传输细粒电量消耗值。本文通过考虑到在计费期结束时,能源供应商收集每个仪表的总体用电来衡量这种方法提供的真实隐私。提出了一种基于熵的措施来量化隐私并确定对仪表整体消耗的知识的程度,可以重新识别匿名的细粒消耗值。
In recent years, many proposals have arisen from research on privacy in smart metering. In one of the considered approaches, referred to as anonymization, smart meters transmit fine-grained electricity consumption values in such a way that the energy supplier can not exactly determine procedence. This paper measures the real privacy provided by such approach by taking into account that at the end of a billing period the energy supplier collects the overall electricity consumption of each meter for billing purposes. An entropy-based measure is proposed for quantifying privacy and determine the extent to which knowledge on the overall consumption of meters allows to re-identify anonymous fine-grained consumption values.
