Abstract
A method includes transmitting data by a first interface card in a trusted domain. A second interface card in an untrusted domain receives the data. The second interface card stores the data in a first memory location of a plurality of first memory locations in the untrusted domain and verifies integrity of the data. The second interface card writes a result of the verifying in a second memory location of a plurality of second memory locations in the untrusted domain. The first interface card retrieves the result of the verifying from the second memory location of the plurality of second memory locations in the untrusted domain. The first interface card creates a table configured to identify and track a state of the second memory location of the plurality of second memory locations in the untrusted domain corresponding to the data received from the first interface card in the trusted domain.
