The following explains the rationale for acceptability in all cases where a dependency is not satisfied:
Rationale for Removing Dependencies on FCS_CKM.4
Once the MFP administrator generates the cryptographic key that is used for the HDD encryption of this
TOE at the start of TOE operation, the cryptographic key will be continuously used for the HDD and will not
be deleted. Therefore, cryptographic key destruction by the standard method is unnecessary.
