Bulletin on Elliptic Curve Cryptography (ECC)  
SCS Volume version 10.0 

Public Consultation
1 - 31 March 2024

The European Payments Stakeholders Group (EPSG, former European Cards Stakeholders Group - ECSG) develops and maintains the "Single Euro Payments Area (SEPA) Cards Standardisation Volume" (hereafter, the Volume). The EPSG is composed of market representatives from the five main payment-related sectors: Payment Service Providers (gathered in the EPC), Processors, Retailers (Merchants), Schemes and Vendors.

The last version of the Volume (10.0) was published on 25 October 2022, taking effect immediately for a three-year period.

The ECSG began addressing the topic of Elliptic Curve Cryptography (ECC) in 2021, prior to the publication of the SEPA Cards Standardisation Volume v10.0. At that stage, even though it was recognised as relevant to incorporate ECC into the Volume, the available documentation was not sufficient to define standardisation requirements. It was necessary to wait until 2024 to be able to publish the relevant updates through this Bulletin before the publication of the next Volume version.

In the meantime, the association has expanded its scope beyond cards becoming the EPSG. This bulletin, although published by the EPSG, is related to Volume v10.0 as published by the ECSG, therefore its ambit is limited to card-based transactions.


Public consultation 

The EPSG is consulting all market participants and stakeholders on the draft Bulletin on Elliptic Curve Cryptography. Based on the outcome, the EPSG plans to publish the Bulletin by June 2024.

The summary results of the contributions will be published with the release v10.0 of the Volume. More information on the consultation process can be found within the 'consultation feedback form' that also allows the submitter to ‘opt out’ their feedback for such a publication.
