Abstract
In this paper we address physical layer security of multiple input multiple output (MIMO) communication system in presence of multiple destinations and passive eavesdroppers. Since the eavesdroppers are passive, it is assumed that channel state information (CSI) of the eavesdroppers are not available at the source. Spatial beamforming and artificial noise broadcasting are chosen as the strategy for securing the transmission. Secrecy capacity for optimum power allocation and uniform power allocation with power constraints are analyzed. Optimum power allocation technique is applied when all the authorized users have different data rates. Uniform power allocation is done when all the authorized users have the same data rate. The analytical results are derived and validated through simulation results and finally it is compared with existing methods.
