In practical applications, one would have several BDKs on record, possibly for different customers, or to contain the scope of key compromise. When processing transactions, it is important for the receiver to know which BDK was used to initialize the originating device. To achieve this, the 80-bit KSN is structured into three parts: as Key Set ID, a TRSM ID, and the transaction counter. The algorithm specifies that the transaction counter is 21-bits, but treats th… WebKSN Field: Enter the ordinal number of the Field ID or the Position that holds the KSN, Encryption Key Serial Number, and Transaction Counter data.
