Supporting both Master/Session
and DUKPT key management methods—one at a time or simultaneously—the PINpad 2000
provides comprehensive security for debit card transactions.An integral part of the PIN encryption process, effective key management is
essential to protecting the customer's PIN against intrusion or corruption. That's why
VeriFone designed the PINpad 2000 to take advantage of both Master/Session and DUKPT
(derived unique key per transaction) key management methods.
Used worldwide, the Master/Session method employs master
keys and working "session" keys to ensure the integrity of debit card
transactions. The DUKPT key management method adds an extra level of security by deriving
a unique key for every debit transaction. This frees processors from maintaining extensive
key records on each merchant, streamlining deployment and inventory management.
Because the PINpad 2000 supports both methods, users
needn't purchase new hardware if their key management requirements change. The PINpad 2000
also supports MAC (Message Authentication Code), a technique that protects the debit
transaction data from accidental or fraudulent tampering during its transfer to the host.
And the PINpad 2000 is compatible with VeriFone's PINpad 201 and 301 applications, saving
the expense of application upgrades.
