    摘要: Embodiments of the present invention are directed to a one-way data transfer system with built-in data verification mechanism, comprising three nodes (Send Node, Receive Node, and Feedback Node) wherein (1) the three nodes are interconnected with each other by a one-way data link, and (2) the Feedback Node is designed solely for processing and relaying data verification information from the Receive Node to the Send Node. In these embodiments, the Send Node is capable of verifying the status of data it transferred to the Receive Node over a one-way data link without sacrificing the unidirectionality of data flow in the system and thereby compromising the level of security provided by use of one-way data links.

While the apparatus is capable of bidirectional communications with either or both of the first and second nodes through the respective interfaces, the unidirectionality of data flow through the apparatus is strictly enforced by the hardware of the apparatus. The apparatus provides a secure mechanism and communication channel for relaying hashed acknowledgment messages from a receive node to a send node to inform the status of data transfer from the send node to the receive node across a one-way data link. The apparatus may be further implemented with the capability of comparing hashed messages from the two nodes.

    摘要: A bilateral data transfer system comprising a first node, a second node, a first one-way link for unidirectional transfer of first data from the first node to the second node, and a second one-way link for unidirectional transfer of second data from the second node to the first node, wherein the unidirectional transfer of the first data across the first one-way link and the unidirectional transfer of the second data across the second one-way link are independently administered by the bilateral data transfer system. Under such bilateral data transfer system, each of the one-way data links may be subject to separately administered security restrictions and data filtering processes. Hence, it enables secure bilateral communications across different network security domains.
