WebSep 2, 2024 · A BDK (Base derivation Key) is a super secret key that are used to derive encryption keys for payment terminals. The BDK is part of the DUKPT (Derived unique key per transaction) scheme as specified in ANSI X9.24 … DUKPT was invented in the late 1980s at Visa but didn’t receive much acceptance until the 1990s, when industry practices shifted towards recommending, and later requiring, that each device have a distinct encryption key. Before DUKPT, state of the art was known as Master/Session, which required every PIN-encrypting device to be initialized with a unique master key. In handling transactions originating …

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.
