Abstract
Two embodiments of a one-way network interface card are disclosed, a transmit-only version and a receive-only version. A network controller mounted on the circuit card is coupled to the host computer via a host computer interface. A first processor is coupled to a network interface of the network controller. A second processor has a separate network interface for communicating with a remote computer. A one-way link is coupled between the first processor and the second processor. For the transmit-only embodiment, the one-way link only allows information to be transferred from the first processor to the second processor, and thus information may only pass from the host computer to the remote computer. For the receive-only embodiment, the one-way link only allows information to be transferred from the second processor to the first processor, and thus information may only pass from the remote computer to the host computer.
