Abstract
A method includes transmitting, by a first interface card in a trusted domain, data. A second interface card in an untrusted domain receives the data. The second interface card stores the data to a first memory location 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 in the untrusted domain. The first interface card in the trusted domain retrieves the result of the verifying from the second memory location in the untrusted domain. The first interface card in the trusted domain determines if the data in the transmitting was received by the second interface card based on the result.
