ACI offers Point to Point Encryption (P2PE) as part of retailer payments solution portfolio. With Point to Point Encryption, service providers and retailers using ACI’s payment systems can ensure that payment data is safeguarded at all times – from the moment the payment information is submitted to the moment that it is stored. Thales Payment HSM, formerly Luna EFT HSM, is a hardware security module (HSM) specifically designed to secure financial transactions. Thales Payment HSM integrates with ACI’s P2PE solutions to ensure that the encryption keys used to secure the transaction are stored out of harm’s way in a FIPS 140-2 Level 3 tamper-proof hardware appliance. By using Thales Payment HSM, retailers are able to account for their encryption keys - and consequently, the security of payment information - at all times because the keys never leave the confines of the hardware appliance. Traditional software storage leaves keys vulnerable to theft, corruption, or loss; Thales Payment HSM eliminates these risks and assures the integrity of payment data from the moment it is generated to the moment it is received by the end-user enterprise.
