FPT_RVM.1

document data stored on the hard disk drive difficult can be realized

by encryption:

FCS_CKM.1

FCS_CKM.1, the cryptographic key of the specified

cryptographic key size is generated.

FCS_COP.1

FCS_COP.1, the document data stored on the hard disk drive

is encrypted and then decrypted when the data is read, in

accordance with the determined cryptographic algorithm and

cryptographic key size.

FPT_RVM.1

FPT_RVM.1, TOE security functions are certainly invoked and

not bypassed.

By the following security functional requirements, O.MANAGE can

be realized:

FIA_AFL.1

FIA_AFL.1, successive attacks are prevented because the

power needs to be cycled when key operator fails in

authentication the set number of times.

- FIA_UID.2 and FIA_UAU.2

FIA_UID.2 and FIA_UAU.2, identification and authentication

are performed before the operation from the control panel or the

Web browser of key-operator’s client when key-operator’s

identification and authentication is needed for the operation.

FIA_UAU.7

FIA_UAU.7, illicit leakage of the authentication information is

prevented because the authentication feedback is protected.

- FMT_MTD.1(1), FMT_MTD.1(2), FMT_MTD.1(3), and

FMT_MOF.1 (1)

“HDD overwriting function for residual data” can be set only by

key operator because:

- by

FMT_MTD.1(1), FMT_MTD.1(2), and FMT_MTD.1(3), the

person who queries and modifies the setting values of the

TOE setting data for “setting for using password,” ”access

denial due to failure in authentication of key-operator’s

ID,” ”cryptographic seed key for data stored on the hard disk

drive,” and ”setting for customer-engineer operation restriction

function” is limited only to the key operator.

- by

FMT_MOF.1 (1), the person who makes settings for the

number of overwritings and erasings of / disables the

function of / enables the function of the TOE security function

“HDD overwriting function for residual data” is limited to key

operator.

FMT_MOF.1 (2)

FMT_MOF.1 (2), “HDD data encryption function” can be set

only by key operator because the person who disables and

enables the TOE security function “HDD data encryption function”

is limited to key operator.

FMT_MOF.1 (3)

FMT_MOF.1 (3), password use of the “key-operator

authentication function” can be set only by key operator because

the person who makes the setting for using password of the TOE

security function “key-operator authentication function” is limited

to key operator.

FMT_SMR.1

FMT_SMR.1, the role related to the security is limited to key

operator by maintaining the role of key operator as a user who

has special authority.

FMT_SMF.1

FMT_SMF.1, security management functions to manage

key-operator’s password are provided.

FPT_RVM.1

FPT_RVM.1, TOE security functions are certainly invoked and

not bypassed.
