Abstract
A system used in a retail environment for providing end-to-end encryption of payment cardholder data. An input device configured to receive cardholder data is operative to encrypt the cardholder data according to a first encryption method to produce first encrypted cardholder data. A cardholder data handling device is in electronic communication with the input device. A secure evaluation assembly (SEA) is operatively connected to the cardholder data handling device and comprises antitampering control electronics adapted to decrypt the first encrypted cardholder data to produce unencrypted cardholder data. The antitampering control electronics evaluate the unencrypted cardholder data to determine whether the unencrypted cardholder data is payment cardholder data or nonsensitive cardholder data. Finally, if the unencrypted cardholder data is payment cardholder data, the antitampering control electronics of the SEA are adapted to encrypt the unencrypted cardholder data according to a second encryption method to produce second encrypted cardholder data.
