What it does in the transaction path
AES and TDES, DUKPT and master/session; ISO 9564 / X9.8 formats 0, 1, 3 and 4; PIN verification by IBM-3624 PIN offset and Visa PVV.
CVV, CVV2, CVC and dynamic CVV (CVC3); MAC generation and verification to ANSI double-key X9.19 and ISO 9797-1 algorithm 3.
X9 TR-31 and AKB key block formats; management of encrypted keys compatible with X9.24-1, X9.24-2, X9.24-3 and ISO 11568; remote key loading and distribution to PIN entry devices and ATMs under TR-34.
EMV v3.x and v4.x transaction processing and secure messaging including PIN change; TDES and AES encryption and decryption in support of PCI DSS; point-to-point encryption using TDES DUKPT and BPS; audit trail.
Algorithms, standards and dual control
Triple DES; AES (FIPS 197); BPS format-preserving encryption; RSA key generation, signing and verification up to 4096 bit (X9.31); ECC from P-224 to P-521; SHA hash algorithms (ISO 10118 / FIPS 180-4); HMAC (FIPS 198-1).
Built-in access control enforces dual control for sensitive operations such as key loading. Appointed security officers enter their passwords on the Prism Key Loading Device to authorise them, and key components are entered the same way.
ANSI X9.8, X9.19, X9.24, X9.31, X9.52, TG-39, TR-31 and TR-34; FIPS 180-4, 186-4, 197 and 198-1; ISO 9564, 10118, 11568, 13491 and 20038.
Mobile security extensions for SMS and mCommerce security, alongside the banking and EFT feature set.
