Abstract
A method includes a processor in a trusted domain receiving a first request having a plurality of messages for a device in an untrusted domain. The processor assigns a memory location having data segments and status segments. The memory location is accessible by an untrusted side interface card. The processor transmits a first message to a first data segment. The processor receives a first value associated with the first message from a first status segment. The processor determines whether the first value indicates that the first message has been received and stores a first representation of a successful data transmission. The processor transmits a second message to a second data segment. The processor retrieves a second value from the second status segment. The processor determines whether the second value indicates that the second message has been received and stores a second representation of the successful data transmission.
