	* DUKPT is a key management method that generates a unique key for each transaction, ensuring the security of transaction-originating TRSMs (Transaction-Related Security Modules).
	* It is designed to prevent the disclosure of any past keys used in transactions.
	* The unique Transaction Keys are derived from a base derivation key, using non-secret data transmitted as part of each transaction.
	* DUKPT allows the encryption process to be decentralized from devices holding the shared secret.
	* Utilizes derived keys for encryption, which are not reused post-transaction, enhancing security.
	* Commonly used in electronic commerce transactions, especially for encrypting PIN information in POS (Point-Of-Sale) devices.
	* DUKPT is not an encryption standard but a technique for managing keys.
	~~== Key Features of DUKPT ==~~
	* '''Distinct Transaction Keys:~~''' Ensures each transaction has a unique key, separate from others~~.
	* '''Security of Past and Future Keys:''' If a current key is compromised, previously and subsequently used keys remain secure.
	* '''No Interactive Key Agreement:''' Avoids the need for originators and receivers of encrypted messages to perform an interactive key-agreement protocol.
	~~== Support in PINPad ==~~
	* Our internal PINPad supports three types of DUKPT keys: PIN key, MAC key, and data key. Each key type is used to encrypt different types of data.
	~~== Key Injection and Usage ==~~
	* '''Key Injection:''' For information on injecting DUKPT keys, refer to [[How to Remotely Inject Test Keys (Master Key or DUKPT Key) into a Terminal]] or [[How to Use TMK Delivery System for KeyLoader POS and Master POS]].
	* '''Usage in SDK:''' Details on using DUKPT keys are available in our SDK, particularly in the description of the PINPad.
	* '''Demo App:''' A [http://~~ftp.wizarpos.com~~/~~advanceSDK~~/~~DukptDemo.zip~~ dukpt ~~demo application] is available for download to demonstrate practical usage.~~

	* If a ~~present derived~~ key is compromised, ~~past~~ and ~~future~~ keys ~~(and thus the transactional data encrypted under them)~~ remain ~~uncompromised,~~		* '''Security of Past and Future Keys:''' If a current key is compromised, previously and subsequently used keys remain secure.
