Abstract

In this paper the fading multiple antenna (MIMO) wire-tap channel is investigated. The secret diversity gain and the secret multiplexing gain are defined. Using these definitions, the secret diversity-multiplexing tradeoff (DMT) is calculated analytically when the source node does not have transmitter side channel state information (CSI). It is shown that the wire-tapper steals degrees of freedom from the source-destination channel, and the secret DMT depends on the remaining degrees of freedom. When CSI is available at the source, unlike the case when there are no security constraints, transmitter CSI changes the secret DMT significantly.
