Abstract

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, enabling secure bilateral communications across different network security domains.

Claims8

Dependent claims

A bilateral data transfer system comprising:

a first one-way link for unidirectional transfer of data from an input end thereof to an output end thereof;
a second one-way link for unidirectional transfer of data from an input end thereof to an output end thereof;
a first node coupled to the input end of the first one-way link and to the output end of the second one-way link, the first node configured to transfer first data over the first one-way link, to receive second data over the second one-way link, and to prevent cross-talk between the first data transferred over the first one-way link and the second data received over the second one-way link;
and
a second node coupled to the output end of the first one-way link and to the input end of the second one-way link, the second node configured to receive the first data from the first node over the first one-way link, to transfer the second data to the first node over the second one-way link, and to prevent cross-talk between the first data received over the first one-way link and the second data transmitted over the second one-way link.
