In a smart grid, a smart meter reports its real-time electricity consumption data to utility supplier periodically, the utility supplier adjusts its supplement accordingly. However, real-time electricity consumption data may reveal the inhabitants’ behaviors, thus smart grid data aggregation schemes are introduced to protect user’s privacy, which enables the utility supplier to get the total consumption data rather than a single meter’s electricity consumption data. However, existing solutions do not solve all the problems, some schemes are not scalable, once the system is deployed, it is unable to add new meters to the system, in some schemes, the electricity consumption data are encrypted using the utility supplier’s public key, if the utility supplier accidentally obtains the encrypted data, it is able to decrypt the data. For these reasons, we designed a scalable elliptic-based multidimensional data aggregation scheme for the smart grid, an independent key is assigned to a meter, even if the utility supplier is unable to decrypt a single meter’s encrypted electricity consumption data. Besides, the proposed scheme is scalable, it is easy to add or remove a meter from the system, and the proposed scheme enables a meter to report multiple types of data at a time.
