Today's electricity grid is evolving into the smart grid which ought to be reliable, flexible, efficient, and sustainable. To fulfill these requirements, the smart grid draws on a plenty of core technologies. Advanced Metering Infrastructure (AMI). These technologies facilitate easy and fast accumulation of different data, e.g. ne-grained meter readings. Various security and privacy concerns w.r.t. the gathered data arise, since research has shown that it is possible to deduce and extract user behavior from smart meter readings. Hence, these meter readings are very sensitive and require appropriate protection.
