Details

This part of the standard describes the AES DUKPT algorithm, which is used to derive key(s) from an initial terminal DUKPT key based on the transaction number. Derived keys can be used for a variety of functions, such as encryption of PINs, data or other keys, for derivation of other keys, for message authentication, etc. AES DUKPT supports the derivation of AES-128, AES-192, AES-256, and double and triple length TDEA keys from AES-128, AES-192, and AES-256 initial keys.
