Ricoh Aficio Common Security Features Guide
Driver Encryption Key
Ricoh devices offer this feature that scrambles user authentication passwords when using the PCL or
RPCS drivers so others cannot access the system fraudulently using a stolen user's password.
PDF Password Encryption
This function corrects a vulnerability in Encrypted PDF Transmission in that the window for entering the
user password displays the password in clear text. This function encrypts passwords up to 32 characters
for more secure PDF transmission and storage. The assignment of a group password for both the
destination machine and connected PCs is done via DeskTopBinder Lite.
SNMP v3 Encrypted Communication
Simple Network Management Protocol version 3
(SNMPv3) is a network management standard
widely used in TCP/IP environments. SNMP
provides a method of managing network hosts
such as printers, scanners, workstation or server
computers, and groups bridges and hubs together
into a "community" from a centrally-located
computer running network management
software. It allows administrators, for example,
to make changes to device settings via
SmartDeviceMonitor from a networked PC with
encrypted communications to maintain a secure
environment.
Earlier versions (v1 and v2) of SNMP were used to configure and monitor remote devices. The latest
version, SNMPv3, offers enhancements to user authentication and data encryption that deliver greater
security features to protect customer data and network assets. When activated, SNMPv3 prevents
unauthorized users from seeing either the password and/or the actual content of the file in readable text
form, protecting valuable information.
S/MIME for Scan to E-mail
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public key encryption and
signing of e-mail encapsulated in MIME (Multipurpose Internet Mail Extensions). MIME is an Internet
Standard that extends the format of e-mail to support text in character sets other than US-ASCII, non-
text attachments, multi-part message bodies, and header information in non-ASCII character sets.
This function is used to encrypt confidential data transmitted by Scan to E-mail for data protection
against wiretapping.
IPsec Communication
IPsec (IP security) is a suite of protocols for securing Internet Protocol (IP) communications by
authenticating and/or encrypting each IP packet in a data stream. IPsec also includes protocols for
cryptographic key establishment. Organizations that require high levels of security have networks with
IPsec for data protection. These organizations require printing using IPsec.
