Controller for event-based statistical covert channels

Patent image
NRL

A controller for an event-based statistical covert channel includes a data receiver; a data transmitter; and a channel controller that includes a fixed distribution randomized event buffer construction processor (FDREBCP) and a fixed distribution randomized event buffer (FDREB). The FDREBCP holds event distribution data that define one or more fixed distributions that the FDREBCP employs to fill the FDREB, whereby the event distribution data is stored during the occurrence of the event, subsequently removed from the FDREB and reordered, and a dummy event distribution data created to prevent an unauthorized outsider modulating the timing of events by alternatively causing and not causing the event.
