Blind secure communication: The Secure degrees of freedom of one hop wireless networks with No CSI

Abstract

We study a number of wireless networks with secrecy constraints and No CSI. The wiretap and MIMO broadcast channels in a presence of an external eavesdropper and the MIMO interference channel with secret messages and no external eavesdroppers are considered. We assume that the transmitters' information is restricted to the channels coherence times and second order statistics rather than the actual channel states. We provide the achievable secure degrees of freedom for each network. ? 2018 IEEE.
