Attack capability of the attackers assumed for this TOE is low level. Therefore, “SOF-basic” being

the minimum function strength level is appropriate. The security function strength necessary for

TOE is satisfied because all the probabilistic and permutational mechanisms in FIA_AFL.1 and

FIA_UAU.2 are SOF-basic.

(4) Dependencies of Security Functional Requirements

Functional requirements that are depended on by security functional requirements and those that

are not are described in Table 17.

Table 17: Dependencies of Functional Requirements

Component Component that is

depended on

Component that is not depended on

FCS_CKM.1 FCS_COP.1 FCS_CKM.4

Cryptographic key is generated when booting MFP, and

stored on DRAM (volatile memory). Cryptographic key

does not need to be destructed because this key is lost

when the power of the mainframe of MFP is shut down.

Therefore, the dependency on FCS_CKM.4 does not

need to be satisfied.

FMT_MSA.2

TOE automatically generates the cryptographic key of the

fixed 128-bit size from the TOE setting data for

“cryptographic seed key for data stored on the hard disk

drive” that is set by key operator.

It is not necessary to assure that only the secure value is

accepted because the size of this cryptographic key that

is automatically generated by TOE is fixed to 128-bit.

TOE always uses the automatically-generated

cryptographic key, and the security attribute other than

the key size does not exist.

Therefore, the dependency on FMT_MSA.2 does not

need to be satisfied.

FCS_COP.1 FCS_CKM.1 FCS_CKM.4

Cryptographic key is generated when booting MFP, and

stored on DRAM (volatile memory). Cryptographic key

does not need to be destructed because this key is lost

when the power of the mainframe of MFP is shut down.

Therefore, the dependency on FCS_CKM.4 does not

need to be satisfied.

FMT_MSA.2

TOE automatically generates the cryptographic key of the

fixed 128-bit size from the TOE setting data for

“cryptographic seed key for data stored on the hard disk

drive” that is set by key operator.

It is not necessary to assure that only the secure value is

accepted because the size of this cryptographic key that

is automatically generated by TOE is fixed to 128-bit.

TOE always uses the automatically-generated

cryptographic key, and the security attribute other than

the key size does not exist.

Therefore, the dependency on FMT_MSA.2 does not

need to be satisfied.

FDP_RIP.1 None None

FIA_AFL.1 FIA_UAU.2 FIA_UAU.1

The dependency on FIA_ UAU.1 is satisfied because

FIA_UAU.2 is the security functional requirement that is

an upper hierarchy of FIA_ UAU.1.

FIA_UID2 None None

FIA_UAU.2 FIA_UID.2 FIA_UID.1

The dependency on FIA_UID.1 is satisfied because

FIA_UID.2 is the security functional requirement that is an

upper hierarchy of FIA_UID.1.

FIA_UAU.7 FIA_UID.2 FIA_UID.1
