(1) Generate appropriate cryptographic keys.
FCS_CKM.1 generates the cryptographic key for encryption.
(2) Perform cryptographic operation.
FCS_COP.1 encrypts the data to be stored in the HDD, and decrypts the data to be read from the HDD.
(3) Manage the TSF data.
FMT_MTD.1 allows the MFP administrator to manage the cryptographic keys.
(4) Specification of Management Function.
FMT_SMF.1 performs the required Management Functions for Security Function.
(5) Specification of the roles.
FMT_SMR.1 maintains the users who have the privileges.
By satisfying FCS_CKM.1, FCS_COP.1, FMT_MTD.1, FMT_SMF.1 and FMT_SMR.1, which are the
security functional requirements for these countermeasures, O.STORAGE.ENCRYPTED is fulfilled.
