■ Security features (encryption key and certificate, password
protection)
● Overview
The main controller PCB 1 of the host machine holds a new PCB named "TPM PCB". "TPM"
stands for "Trusted Platform Module", which collectively refers to the chip set for generating
and storing encryption keys and computing public key encryption.

The TPM PCB protects security information (passwords, certificates, and encryption keys)
stored in the HDD and SRAM. Note that this PCB does not protect set, registered or stored
data other than security information.
The TPM key embedded in the chip is used to encrypt / decrypt security information. The
TPM key is protected from illegal access in a virtually perfect manner, thus the security
information of the host machine is securely protected even in the following conditions.
• When the HDD and / or the main controller PCB is taken out from the host machine and
installed in the MFP with the different serial number (the model information held in the TPM
PCB is specific to the machine originally enabled the TPM setting)
• When the system of the host machine is hacked via the network
Enable this function in Setting / Registration mode.
