FIPS197 AES 256 bits
Following operations by the MFP administrator, the TOE generates a cryptographic key. If a login user is the
MFP administrator, the screen to generate an HDD cryptographic key is provided from the Operation Panel.
If the MFP administrator gives instructions to generate an HDD cryptographic key from the Operation Panel,
the TOE uses a genuine random number generator and generates random numbers that conform to the
standard BSI-AIS31.
7.8 Security Management Function
The Security Management Function consists of functions to 1) control operations for TSF data, 2) maintain
user roles assigned to normal users, MFP administrator, or supervisor to operate the Security Management
Function, and 3) set appropriate default values to security attributes, all of which accord with user role
privileges or user privileges that are assigned to normal users, MFP administrator, or supervisor.
FMT_MSA.1(a), FMT_MSA.1(b), FMT_MSA.3(a), FMT_MTD.1, FMT_SMF.1 and FMT_SMR.1
The TOE allows operations for TSF data according to the rules described in Table 39.
