ABSTRACT

In this paper, the information-theoretic secrecy for the log-normal fading channel is investigated. In particular, the closed-form expressions of the probability of strictly positive secrecy capacity are derived for two wireless communication systems, with single eavesdropper and double eavesdroppers, respectively.
