Development Devices
A development device is a V
x
810 still maintaining the original factory set of
certificates in its certificate tree. This set of certificates includes several higher-
level system certificates and a special client certificate called a default signer
certificate.
In the development device, the level of logical security provided by the file
authentication module is minimal, even though applications must still be signed
and authenticated before they can run on the device. In most application
development and test environments, tight security is not required, and the
flexibility offered by the V
x
810 development device is more important.
Deployment Devices
While the application development process is being completed and while the new
application is being tested on a development device, a sponsor can order specific
sponsor and signer certificates from the VeriFone CA to use to logically secure
sponsor and signer privileges when the V
x
810 is prepared for deployment.
Customer-specific sponsor and signer certificates are usually downloaded onto a
device as part of the standard application download procedure performed by a
deployment service. In this operation, the new sponsor and signer certificates
replace the development sponsor certificate that is part of the factory set of
certificates.
When the sponsor and signer certificates are downloaded and successfully
authenticated, the device is ready to deploy.
NOTE
With the factory set of certificates stored in the device’s memory, anyone who
has the V
x
810 SDK and VeriShield File Signing Tool can generate valid signature
files for downloading and authenticating files on the V
x
810 platform.
