In embodiments, the system includes first and second random number generators, each generating a one-time pad for transmission to both a corresponding front-end cryptographic engine and a parallel guard engine. The cryptographic engines double encrypt the data packet in sequence according to the one-time pads, storing the encrypted packet in a holding register. Each guard engine inspects the data packet in parallel, indicating approval by transmitting a release to the holding register and sending its one-time pad to a back-end cryptographic engine. When the holding register receives both releases, the double encrypted packet is sequentially decrypted by the back-end cryptographic engines in reverse order according to the one-time pads received from the guard engines. The fully decrypted data packet is transferred to the second domain."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Parallel cross-domain guard engines with sequential cryptographic controls","description":"A system and method for cross-domain parallel inspection of data packets in transit between domains of differing security classification incorporating sequential cryptographic control is disclosed.
