A system for providing postal and other services to postal security devices is established in which a secured communication connection is obtained through a service provider. The connection once established provides access to a central postal data center. As part of the authentication of a connection by the service provider, the service provider generates a session key having a discrete time limit. Expiration of the time limit terminates the session key. Security keys are provided to the service provider, with reference to public keys of the service provider, by the data center communication infrastructure.
