METHODS AND SYSTEMS FOR SECURE MESSAGE TRANSMISSIONS BETWEEN TRUST DOMAINS

A computer device for routing communications from a low-trust domain to a high-trust domain is provided. The computer device includes a first processor and a second processor. The first processor is programmed to receive a packet from the low-trust domain to be transmitted to the high-trust domain and compare the source address to a white list of source addresses. If the source address matches the white list, the first processor is programmed to compare the message to one or more messaging requirements. If the message meets the one or more messaging requirements, the first processor is programmed to write the message to a memory. The second processor is programmed to read the message from the memory and compare the message to a plurality of stored values. If the message matches the plurality of stored values, the second processor is programmed to act upon the message.
