Covert channel is one of the remarkable issues which
are raised in computer network security. These channels use the
computer network’s resources to transmit information furtively.
Since the purpose of covert channels is to stay hidden from the
network security equipments, hence their detection will be
difficult. The growth of wireless networks and their broadcast
nature make them suitable environments for covert channels’
establishment. This study proposes a method to create a covert
channel in local area wireless networks by using the temporal
characteristics of CSMA/CD algorithm and manipulating the
transmission pattern. To increase the bandwidth, hidden data is
considered ternary. To assess the covertness of the proposed
covert channel, two-sample Kolmogorov-Smirnov test is used.
The proposed covert channel achieves the bandwidth of 1620 bps
with a high level of security.
