    • description: PRODUCT DESCRIPTION The TOE is a firmware intended to reduce the danger against the disclosure of document data and image data that are temporarily spooled in the Multi-Function Device (hereafter referred to as “MFD”). TOE is offered as an upgraded kit for firmware of the MFD. The TOE provides security function to counter the threat against document data and image data that are temporarily spooled in the Mass Storage Device ( hereafter referred to as MSD) which is defined for each configuration of the functional unit in M FD. When MFD executes basic function as copy, print, Fax or image scanning, MFD executes data encryption before spooling document image data in MSD. Moreover MFD erases image data in MSD automatically after finishing copy, print, Fax or image scanning jobs or at the time of power-on. As a result, MFD keeps high confidentiality of the document/ image data in MSD, and it opposes fraudulent disclosure.

    • description: The TOE is a combination of hardware and software configured to securely create, use, and manage Signature Creation Data (SCD). The SSCD protects the SCD during its whole life cycle as to be used in a signature creation process solely by its Signatory. The TOE comprises all IT security functionality necessary to ensure the secrecy of the SCD and the security of the electronic signature. The TOE provides the following functions: to generate Signature Creation Data (SCD) and the corresponding Signature Verification Data (SVD), to export the SVD for certification to the CGA over a trusted channel, to prove the identity as SSCD to external entities, to, optionally, receive and store certificate info, to switch the SSCD from a non-operational state to an operational state, and if in an operational state, to create digital signatures for data with the following steps: select an SCD if multiple are present in the SSCD, authenticate the Signatory and determine its intent to sign, receive data to be signed or a unique representation thereof (DTBS/R) from the SCA over a trusted channel, apply an appropriate cryptographic signature creation function to the DTBS/R using the selected SCD.
