This paper is concerned with the study of secrecy capacity for the log-normal fading channel in which the main channel is correlated with the eavesdropper channel. Perfect secrecy is achieved when the transmitter and legitimate receiver can communicate at some positive rate, while insuring that the eavesdropper gets zero bits of information. The authors consider the full Channel State Information (CSI) case, where the transmitter has access to both the main channel and eavesdropper channel gains. Under this assumption, they define the secrecy capacity of Single-Input Single-Output (SISO) log-normal fading channel and find the optimal power allocation at the transmitter that achieves the secrecy capacity.
