The smart-grid is gaining increasing attention nowadays, owing to its premise to offer increased reliability and performance. However, the current design of smart-grids raises serious concerns with respect to the privacy and anonymity of users. In this paper, we address the problem of enhancing the privacy of users in the smart grid throughout the reporting and the billing phases. To that end, we propose a taxonomy of solutions that enable (i) the privacy-preserving aggregation of smart meters' energy consumption reports without relying on a single point of trust, (ii) the anonymous tasking, e.g., the outsourcing of (maintenance) tasks to smart meters, and (iii) the privacy-preserving billing and barter of energy between the utility provider and the smart meters. To the best of our knowledge, this is the first contribution that comprehensively addresses privacy issues in the tasking and energy-trading processes in smart grids. Our proposed solutions complement previous work in the area and can be easily integrated within existing smart grids.
