WebAug 12, 2024 · The assessor has asserted that mixed sizes of BDKs can be used with DUKPT, based on his reading of ANSI X9.24-1 (2009). Is that true? Can DUKPT encrypt plaintext with an IPEK derived from a 2-key BDK and successfully decrypt that data from that same IPEK in a decryption environment with a 3-key BDK? WebBDK: This is an acronym for Base Derivation Key. This key is known only to the manufacturer and the software developer interfacing with the magstripe scanner. IPEK: This is an acronym for Initial Pin Encryption Key. This key is derived from the BDK. This key is injected onto the device by the manufacturer and is used to derive future keys.
