Abstract
A method, computer program product and system are provided to provide control mechanisms in unidirectional data transfers. A processor connects to a secure device via a unidirectional connection. A processor sends a packet to the secure device via the unidirectional connection. A processor receives, from the secure device via a passive out-of-band channel, feedback regarding the transmission of the packet. A processor, in response to the feedback indicating that the packet was incorrectly received, resends the packet via the unidirectional connection with the secure device.
