  This paper proposes a new linear precoding scheme for downlink transmission
in MIMOME channels, referred to as secure regularized zero forcing. The scheme
modifies regularized zero forcing precoding, such that the beamformers further
suppress the information leakage towards the eavesdroppers. The proposed scheme
is characterized in the large-system limit, and a closed-form expression for
the achievable ergodic secrecy rate per user is derived. Numerical
investigations demonstrate high robustness against the quality of
eavesdroppers' channel.
