EMV ECC Key Establishment Protocols

1994-2012 EMVCo, LLC (“EMVCo”) — 4 p.EMVCo is investigating new ECC-based mechanisms for protecting the communications between a card and terminal. EMVCo has identified two candidate mechanisms for establishing a shared secret seed between card and terminal at the beginning of the transaction. This seed will then be used for deriving a session key that will be used for protecting all subsequent messages between card and terminal using a standard authenticated encryption method. The first mechanism has better performance than the second mechanism.
