Abstract:
Development of Smart Grid and deployment of smart meters in large scale has raised a lot of concerns regarding customers’ privacy. Consequently, several schemes have been proposed to overcome the above mentioned issue. These schemes mainly rely on data aggregation as a method of protecting users’ privacy from the grid operators. However, the main problem with most of these schemes is the fact that they require a large amount of processing power at the meter side. This, together with the fact that smart meters don’t usually have a powerful processor, can cause the unavailability of smart meter data at the required time for operators of the grid, and at the same time disables smart meters from performing their other duties, such as managing the home area network. In this thesis, we propose two efficient privacy preserving data aggregation schemes, one based on elliptic curves and the other based on a traceable signature. We provide security analysis of the proposed schemes as well as comparisons to show the efficiency of our schemes on computation and communication overheads
