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. While Adobe offers a number of security-related features within the Acrobat application to lock and password-protect documents, there is nothing to prevent 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 changes to or extract content from the document. (See also PDF Password Encryption.) 12
