First a definition:
Derived unique key per transaction (DUKPT) is a key generation method
where a large number of distributed terminals communicate with a few
centralized entities (acquirers).
In DUKPT each terminal is equipped with a base key which is a shared
secret known only by the terminal and the acquirer. The unique
transaction keys are derived from the base key and non secret
transaction information.

The DUKPT is an ANSI standard (X9.24). You can order the document at
http://webstore.ansi.org/ansidocstore/product.asp?sku=ANSI+X9%2E24%2D1998
It costs $120.00. I don't know if a 'pirate' or 'warez' version is available.

DUKPT uses DES (a triple-DES version seems to be around as well).
