摘要： A method for operating a smart grid including a plurality of smart meters, said smart meters being configured to monitor at least one physical measured quantity and to provide measurement results of said at least one physical measured quantity to a central entity, is characterized in the following steps: said smart grid is partitioned into groups G of smart meters sm i , such that each of said smart meters belongs to exactly one group, all smart meters sm i of one of said groups G encrypt their measured value e i by applying a bihomomorphic encryption scheme E ki and send it to said central entity, one smart meter per group is designated as key aggregator to which all smart meters sm i of that group send their key k i employed for said encryption, said key aggregator computes the aggregation of all received keys k i and sends the aggregated key K to said central entity, said central entity aggregates all received encrypted measured values e i and decrypts said aggregation by employing said aggregated key K . Furthermore, a corresponding smart grid is disclosed.
