ABSTRACT:
Disclosed are communication apparatus, a SATA communication device, a system, an enhanced port multiplier and a method for, among other things, establishing a covert communication channel in a protocol-compliant link. In one embodiment, a communication apparatus includes a link interface and a supplemental message interface. The link interface is configured to communicatively couple the communication apparatus to the link for accessing a data stream passing through the link in accordance with a standardized protocol. The supplemental message interface is configured to exchange a supplemental message within the data stream to establish a covert communication channel in the link. The supplemental message supplements the standardized protocol without violating the protocol.
