On the Secrecy Capacity of Fading Wireless Channel with Multiple Eavesdroppers

Abstract

This paper studies the secrecy capacity of fading wireless channel in presence of multiple eavesdroppers. The eavesdroppers are mutually independent and the information is secure if it cannot be eavesdropped by any eavesdropper. We first generalize the work in (J. Barros and M.R.D. Rodrigues, 2006) into multiple-eavesdropper case and investigate the secrecy capacity in terms of outage probability and outage capacity. We show that the results presented in (J. Barros and M.R.D. Rodrigues, 2006)serves as some special cases of our works. We also characterize the ergodic secrecy capacity of fading wireless channel with multiple eavesdroppers. Our work gives the analytical results of secrecy capacity with different number of eavesdroppers.This paper studies the secrecy capacity of fading wireless channel in presence of multiple eavesdroppers.
