The SSL Certificate is a digital "key" that must first be installed on both the device and the sending PC

via Web Image Monitor or SmartDeviceMonitor. Think of the SSL Certificate as an electronic credit card

that verifies the user's credentials and gives/denies permission to send data to a networked device in a

way that cannot be understood or reassembled by anything other than the destination unit.

The NDPU/SSL Certificate perform two functions:

1. Encrypts entire files using the IPP (Internet Printing

Protocol) by reassembling scrambled blocks of data sent

to it from a PC into proper order for printing.

2. Requires entry of an encrypted password to print a PDF

file. The user must enter a corresponding password at the

printer to output the file, or the print job will be cancelled.

Address Book Encryption

Address Book Encryption protects contact information by encrypting the data stored in a system's

address book. Even if the HDD is physically removed from the unit, the data cannot be read. This

function eliminates the danger of a company's or department's entire population of employees,

customers, or vendors being targeted for malicious e-mail messages or PC virus contamination. Further,

since address book data usually corresponds to user names and passwords used elsewhere on the

network, protecting printer/MFP address book data increases overall network security.

Encrypted PDF Transmission

Adobe's PDF file format has become the universal standard for creating documents that can easily be

opened and shared by any user on any platform. Adobe provides the Acrobat® Reader® application as a

free download across the Web. A PDF file is essentially a snapshot of a document. It is unchangeable

(although files are editable with the full Adobe Acrobat application) and therefore attractive to document

owners that wish to share, but restrict alterations, to approved documents. Part of the attraction of the

PDF format is that file sizes are drastically reduced versus those of the native application, making them

easier and faster to e-mail.

changes to or extract content from the document. (See also PDF Password Encryption.)

While Adobe offers a number of security-related

features within the Acrobat application to lock and

password-protect documents, there is nothing to pre-

vent the files from being intercepted in a decipherable

form while traveling over the network. That's where

Ricoh's Encrypted PDF Transmission function adds

value, scrambling and encrypting the data that would

otherwise be a very transparent document during

transmission. Users may choose between 40-bit and

128-bit encryption, and set recipient rights to allow
