2) Entering A Master Key
Master Key security requires that no one person has access to all parts of the key. To ensure this, the
processor will provide keys in separate sealed envelopes (sometimes referred to as "key
components"). Each envelope contains either one or two 16 digit keys and in the case of unique key,
a serial number. The diagram below shows a sample Unique Key, TDES master key.
The Edit Master Key interface is designed so that Parts A and B can be entered at completely different
times and in either order (Part A first, or Part B first). If a technician is dispatched to enter a key part,
choose Check Key from the Key Management menu to determine which part of the key has already
been entered.
Master Key Installation
Begin by choosing Edit Master Key from the menu
Depending on Key Mode, the menu prompts for
Part A and Part B.
Partially entered keys will appear in the index as
#### or **** which denotes that either part A or
part B has been successfully entered. (A = #, B =
*)
This would tell the second technician that they
need to enter their key as Part B on index 12.
Part1 = Part A / Part2 = Part B
