Abstract

A twophase beamforming solution for secure communication using untrusted relay nodes is presented To thwart eavesdropping attempts of participant relay nodes we deliberately introduce artificial noise in the source message We observe that for certain scenarios the source node prefers to allocate its full power to the message signal and therefore in the absence of artificial noise such transmissions will be vulnerable to eavesdropping Therefore we provide a signaltonoise ratio SNR based framework for secure communication We intend to bring down the SNR at each of the untrusted relay nodes below a certain predefined threshold whereas using beamforming we want to boost the SNR at the destination With this motive we evaluate the optimal scaling vector for the beamforming phase which not only nullifies the artificial noise transmitted initially but also maximizes the SNR at the destination We discuss both the total and individual power constraint scenarios and provide an analytical optimal solution and an iterative algorithm respectively
