Abstract

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.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal IEEE Systems Journal due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2020, it was in position 63/273, thus managing to position itself as a Q1 (Primer Cuartil), in the category Engineering, Electrical & Electronic.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.04. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 1.01 (source consulted: FECYT Mar 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2026-04-25, the following number of citations:

  • WoS: 19
  • Scopus: 24
  • Google Scholar: 24

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-25:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 21.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 21 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/86131/

As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of
