Cryptographic key generated as IPSec (ESP: Encapsulating Security Payload) at every session
Specifically, one of the following combinations between secret-key cryptographic method and
hash method is adopted:
Cryptographic Method and Size
of Secret Key
Hash Method
AES / 128 bits SHA-1
3-Key Triple-DES / 168 bits SHA-1
c) SNMPv3
According to the SNMP v3 communication which is configured by a system administrator using
the system administrator mode, SNMP v3 is supported. This is one of the security solutions for
the network management protocol, SNMP. As defined in IETF RFC3414, SNMP v3 is used for
not only data encryption but also authentication of each SNMP message.
To enable this function, both authentication password and privacy password need to be set up in
both the TOE and the remote server. Length of both passwords must be 8 characters or more.
Authentication of SNMP v3 uses SHA-1 hash function; encryption of the protocol uses
CBC-DES. A cryptographic key is generated at the time of starting a session and lost at the time
of ending the session or powering off the MFD main unit.
Cryptographic key generated as SNMP v3 at every session:
Cryptographic Method and Size
of Secret Key
Hash Method
DES / 56 bits SHA-1
d) S/MIME
According to the S/MIME communication which is configured by a system administrator using
the system administrator mode, S/MIME ensuring secure mail communication is supported. This
protects the security of document data on the internal and external networks.
By S/MIME encrypting mail function, the document data being transmitted to/from the outside by
E-mail are protected from interception. By S/MIME signature mail function, the document data
are protected from interception and alteration.
A cryptographic key is generated at the time of starting mail encryption and lost at the time of
completion of the encryption or powering off the MFD main unit.
