Elliptic curve cryptography6/15/2023 In an EMV chip payment, when a card is used at a merchant payment terminal, the terminal can cryptographically authenticate the card and its data by verifying digital signatures that were generated by the card, its issuer and the payment system. Cryptography is one of these layers of protection. Michael Ward: The payment community approaches security in ‘layers’, using many different techniques to combat fraud. In this Q&A post, Michael Ward, Chair of the EMVCo Security Working Group, details the benefits to the payment community of introducing this cryptographic standard into the *EMV Chip SpecificationsĬan you begin by explaining the role cryptographic standards play within EMV Chip Specifications? ![]() In October 2021, EMVCo published a technical specification update to enable EMV ® chip cards to support Elliptic Curve Cryptography (ECC). ![]() ![]() Posted on by Michael Ward in Announcements & Updates
