12.2.2 Downloading Passenger Count Data per USB Stick
The passenger count data downloads is secured by the use of the SHA-512 hash
function. The RS232 plug allows for complete access to the data from a USB stick.
The USB stick has an individual identification name. Authentication is done by key
comparison; if the key does not correspond, access is aborted. Attempted access
failures are recorded in the log file. The SHA-512 must be available to generate the
key file. The key file on the USB stick is always called „vssAuthKeyStick“.
