(EN) SYSTEMS AND METHODS FOR OPTIMIZED RETAIL MESSAGE AUTHENTICATION CODE PROCESSING
(FR) SYSTÈMES ET PROCÉDÉS DE TRAITEMENT DE CODE D'AUTHENTIFICATION DE MESSAGE DE VENTE AU DÉTAIL OPTIMISÉ
Abstract
(EN)
According to some embodiments, systems, methods and computer program code are provided to generate a retail message authentication code (MAC) which includes loading a first key, loading a second key, issuing a first call to a cloud hardware security module (HSM) to invoke a DESS encryption operation, the call including the first key and a first input set of data, receiving an output of the first call, issuing a second call to a cloud HSM to invoke a DESS encryption operation, the call including the second key and a second input set of data, the second input set of data including data associated with the output of the first call, receiving the generated retail MAC.
