  File authentication is a secured process for authenticating files using digital signatures, cryptographic keys, and digital certificates. This process makes it possible for the sponsor of a VX 520 terminal to logically secure access to the terminal by controlling who is authorized to download application files to that terminal.

• Page 76: Special Files Used In The File Authentication Process

  VX 520 clients—either internally within VeriFone or externally to sponsors. All certificates issued by the VeriFone CA for the VX 520 platform, and for any VeriFone platform with the VeriShield security architecture, are hierarchically related. That is, a lower-level certificate can only be authenticated under the authority of a higher-level certificate.

• Page 77
  To establish the logical security of applications to download to a VX 520 terminal, the designated signer uses the signer private key issued by the VeriFone CA as this is a required input to the VeriShield File Signing Tool.
