"Table 6.2 Correspondences between security objectives and TOE security
functional requirements" rationale is described below.
O.OVERWRITE
It is ensured that any previous information content of a resource is made
unavailable upon the deallocation of the resource from the image data file stored
in the HDD in accordance with FDP_RIP.1 Subset residual information protection.
Therefore O.OVERWRITE can ensure that the residue data shall not be reused.
O.ENCRYPT
It can be ensured that the image data stored in the HDD is encrypted in
accordance with FCS_COP.1 cryptographic operation policy.
FCS_COP.1, it is ensured that a cryptographic key enabling encryption is generated
according to FCS_CKM.1. At this time, the cryptographic key is generated every
time power is turned on, using the Kyocera Mita's standard cryptographic key
generation algorithm.
Therefore O.ENCRYPT can ensure that the stored data shall not be illegally
decoded.
