(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.
O.RCGATE.COMM.PROTECT
O.RCGATE.COMM.PROTECT is the security objective to ensure the communication data between the TOE
and RC Gate are concealed, and any tampering on the communication path is detected. To fulfil this security
objective, it is required to implement the following countermeasure.
(1) Use trusted channel for the communication with RC Gate
FTP_ITC.1 allows the TOE to establish the communication that protects the data from tampering and
disclosure for the communication between the TOE and RC Gate.
By satisfying FTP_ITC.1, which is the security functional requirement for this countermeasure,
O.RCGATE.COMM.PROTECT is fulfilled.
