摘要: Traditional electricity meters are replaced by Smart Meters in customers' households. collect fine-grained utility consumption profiles from customers, which turn enables the introduction of dynamic, time-of-use tariffs. However, usage data that is compiled this process also allows to infer inhabitant's personal schedules and habits. We propose a privacy-preserving protocol billing with tariffs without disclosing actual profile supplier. Our approach relies on zero-knowledge proof based Pedersen Commitments performed plug-in privacy component put into communication link between Meter supplier's back-end system. require no changes hardware only small software In paper we describe functional requirements, specification security our solution give performance evaluation prototypical implementation.
