6.2 Software Security Verification
The Casinomate can perform a comparative verification of the program that is used to operate the
validator, and the configuration data loaded in to customise the validator for a specific job.
As part of the verification procedures, a ‘seed’ number is entered, and this is used, with a CRC
check, to generate a number. This number can then be compared to the verification numbers
generated by other validators of the same type, to check whether anything is different or
changed.
To verify the validator, press 3 from the diagnostics main menu.
SERIAL NO= XXXX
SOFTWARE REV= X.XX
CONFIG NO= XXXXX-XX
VERIFY Y/N?
The serial number of the validator will be displayed, along with the software revision number, and
the config number. To proceed with the verification, press YES.
VAL S/N= XXXX
ENTER SEED
ESC
Enter a seed number, for example
1, 2, 3
,
4
ENTER
.
CALCULATING
PLEASE WAIT!
SEED=1234
The display will now show the results of the verification.
VAL S/N= XXXX
CONFIG CRC= XXXXX
ROM CRC= XXXXX
ESC
•
The Config CRC is the checksum of the seed number, and the config data stored in the
validator. This number can be compared to a previous reading taken from the same
validator, or from another validator with the same config, to see if there are any changes
in the code.
•
The ROM CRC is the checksum of the seed number and the program software in the
validator, and can be used to verify that there haven’t been any changes to the operation
of the
validator
