Devices inspect all downloaded firmware packages for a number of required attributes before adopting and executing
the packages. The firmware must be packaged in a proprietary format and encrypted with a symmetric encryption
algorithm through an embedded key that is known only to Lexmark. However, the strongest security measure comes
from requiring all firmware packages to include multiple digital 2048-bit RSA signatures from Lexmark. If these
signatures are not valid, or if the message logs indicate a change in firmware after the signatures were applied, then
the firmware is discarded.
