Storage-based network covert channels operate by altering
the content of some resource that can be observed by a re-
ceiver [5]. Cabuk describes the implementation of a simple
binary storage-based covert channel in [5]. This channel op-
erates using a timeline divided into intervals of size t, known
by both the sender and receiver. The sender transmits a bit
value of 0 by maintaining silence throughout a given inter-
val, and transmits a bit value of 1 by sending a packet or
becoming active during a given interval.
