PRODUCT DESCRIPTION
Description of TOE
The TOE is firmware to enhance security functionality of a Multi-Function Device (hereafter referred to as "MFD"). It is an option that implements security functions and controls the entire MFD when installed instead of the MFD standard firmware.
TOE security functions
As countermeasures against information leakage that residual image data in the MFD induce, the TOE has such security functions as cryptographic operation and data clear. The cryptographic operation function encrypts the image data of each job for PC-Fax, fax send and fax reception before spooled to the Flash memory in the MFD. The data clear function overwrites random or fixed values over the storage area that the spooled image data occupy when the MFD finishes or aborts each job of copy, printer, image send, PC-Fax, fax send, and fax reception functions.
