| 20120042357 | Secure one-way data transfer system using network interface circuitry - Network interface circuitry for a secure one-way data transfer from a sender's computer (“Send Node”) to a receiver's computer (“Receive Node”) over a data link, such as an optical fiber or shielded twisted pair copper wire communication cable, comprising send-only network interface circuitry for transmitting data from the Send Node to the data link, and receive-only network interface circuitry for receiving the data from the data link and transmitting the received data to the Receive Node, wherein the send-only network interface circuitry is configured not to receive any data from the data link, and the receive-only network interface circuitry is configured not to send any data to the data link. The network interface circuitry may use various interface means such as PCI interface, USB connection, FireWire connection, or serial port connection for coupling to the Send Node and the Receive Node. | 02-16-2012 |
| 20120017079 | Secure Acknowledgment Device For One-Way Data Transfer System - An apparatus for relaying a hashed message from a first node to a second node, comprising an inlet interface for receiving a message from the first node, a hash number calculator for hashing the message from the inlet interface, an outlet interface for sending the hashed message to the second node, a first one-way data link for unidirectional transfer from the inlet interface to the hash number calculator, and a second one-way data link for unidirectional transfer from the hash number calculator to the outlet interface, is provided. 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. | 01-19-2012 |
| 20110252116 | BILATERAL COMMUNICATION USING MULTIPLE ONE-WAY DATA LINKS - Bilateral communication using multiple one-way data links for data transfers in opposite directions, each of which is subject to separately administered security restrictions and data filtering processes. Operating together, they enable secure bilateral communications across different network security domains. | 10-13-2011 |
