Therefore, if a derived key is compromised, future and past transaction data are still protected since the next or prior keys cannot be determined easily. DUKPT is specified in ANSI X9.24 part 1.DUKPT allows the processing of the encryption to be moved away from the devices that hold the shared secret. The encryption is done with a derived key, which is not re-used after the transaction. DUKPT is used to encrypt electronic commerce transactions. While it can be used to protect information between two companies or banks, it is typically used to encrypt PIN information acquired by Point-Of-Sale (POS) devices.DUKPT is not itself an encryption standard; rather it is a key management technique. The features of the DUKPT scheme are: enable both originating and receiving parties to be in agreement as to the key being used for a given transaction, each transaction will have a distinct key from all other transactions, except by coincidence, if a present derived key is compromised, past and future keys (and thus the transactional data encrypted under them) remain uncompromised, each device generates a different key sequence, originators and receivers of encrypted messages do not have to perform an interactive key-agreement protocol beforehand."@en }
