A computer-automated method for securing unidirectional communication within a network. The method includes orchestrating an automated arrangement and/or coordination of at least one portion of a message using a top-level orchestration server, transmitting a first data packet from the top-level orchestration server to a first top-level backbone server, wherein the first data packet is a first portion of the message, and authenticating the first data packet using the first top-level backbone server. The method can include transmitting a second data packet from the first top-level backbone server to a second top-level backbone server, wherein the second data packet is a second portion of the message and/or the second data packet includes a modified first data packet and authenticating the second data packet using the second top-level backbone server.
