Abstract
A manifest transfer engine for a one-way file transfer system is disclosed. The manifest transfer engine comprises a send side, a receive side, and a one-way data link enforcing unidirectional data flow from the send side to the receive side. The send side receives and stores a file manifest table from an administrator server. The send side also receives a file from a user and compares it with the file manifest table. Transfer of the file to the receive side via the one-way data link is allowed only when there is a match between the file and the file manifest table. In an alternative embodiment, the receive side instead receives and stores the file manifest table from the administrator server and compares it with the file received from the send side via the one-way data link to determine whether to allow transfer of the file.
