Abstract

A system is disclosed that provides an authenticated payload, e.g., a software program or update, to a recipient device. A storage device stores a payload. A provider server coupled to the storage device outputs the payload and a manifest table. The manifest table includes information identifying the payload. A manifest engine TX server receives the payload and the manifest table from the provider server, generates information about the received payload, compares the information generated about the payload with the contents of the received manifest table, and, if the information about the received payload matches information for a particular one of the at least one payloads included in the received manifest table, forwards the payload to a one-way data link. The output of the one-way data link is coupled to a manifest engine RX server, which in turn forwards any received payload to a recipient device coupled to an output of the manifest engine RX server.
