Updating firmware

Automated firmware updates can be done simultaneously over a network of printers. For security, the ability

to perform this update can be restricted to authorized administrators by using access control.

Printers inspect all downloaded firmware packages for required attributes before adopting and executing the

packages. The firmware is 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.
