Chapter 5: NCR 5945 Diagnostics Specification
Encryption Test
The encryption diagnostics test the security module with an internally
defined account number and PIN. The output of this function can be
used to verify that the correct key has been injected at the designated
index. The test may be done in either Master Session or DUKPT mode.
Select ENCRYPTION TEST from the DIAGNOSTICS menu.
ENCRYPTION TEST
Master / Session
The Master / Session mode displays. Press the Yes and No keys to
toggle between the Master / Session and DUKPT modes. Press Enter
to select and test the displayed mode.
The Encryption Test allows cryptographic confirmation of injected PIN
encryption keys; generates and displays an encrypted PIN block from a
known PIN and account number as defined by VISA documentation.
Note:
Test Encrypt
will work with Master/Session keys as well.
If Master / Session is selected, the NCR 5945 performs the encryption
and displays the 16 characters generated. This indicates the encrypted
PIN block. The numbers generated will be the same for each NCR 5945
with the same Master/Session keys.
Press any key to return to the Test Encrypt menu.
If DUKPT is selected, the NCR 5945 performs the encryption and
displays 2 lines. The first line of 16 Characters represents the
encrypted PIN block. The second line of 20 characters represents the
KSN (Key Serial Number)
Press any key to return to the Test Encrypt menu.
Note:
The NCR 5945 must have had a key injected in order for
this test to perform correctly.
Note:
Test encrypt works by building an ANSI PIN block with
a known account number and PIN as defined in the VISA
document “Point-of-Sale Equipment Requirements”, PIN
Processing and Data Authentication, International Version 1.0,
August, 1988.
