session and lost at the time of ending the session or powering off the MFD main unit.

Cryptographic key generated as TLSv1.0/TLSv1.1/TLSv1.2 upon every session
Specifically, one of the cryptographic suites below is adopted:
Cryptographic Suites of SSL/TLS
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_256_CBC_SHA256
Protection from the alteration is realized by HMAC (Hashed Message Authentication Code -
IETF RFC 2104) of SSL/TLS.
When SSL/TLS communication is enabled on the Web client, requests from the client must
be received via HTTPS. The SSL/TLS communication needs to be enabled before IPSec, or
S/MIME is enabled or before security audit log data are downloaded by a system
administrator.
b) IPSec
According to the IPSec communication which is configured by a system administrator using
the system administrator mode, IPSec ensuring secure data transmission is supported. This
protects the security of document data, security audit log data, and the TOE setting data on
the internal network.
IPSec establishes the security association to determine the parameters (e.g. private key and
cryptographic algorithm) to be used in the IPSec communication between the TOE and the
remote. After the association is established, all transmission data among the specified IP
addresses are encrypted by the transport mode of IPSec until the TOE is powered off or reset.
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.
