  In this paper the secrecy problem in the cognitive statedependent
interference channel is considered. In this scenario we have a primary and a
cognitive transmitter-receiver pairs. The cognitive transmitter has the message
of the primary sender as side information. In addition, the state of the
channel is known at the cognitive encoder. So, the cognitive encoder uses this
side information to cooperate with the primary transmitter and sends its
individual message confidentially. An achievable rate region and an outer bound
for the rate region in this channel are derived. The results are extended to
the previous works as special cases.
