  An information-theoretic confidential communication is achievable if the
eavesdropper has a degraded channel compared to the legitimate receiver. In
wireless channels, beamforming and artificial noise can enable such
confidentiality. However, only distribution knowledge of the eavesdropper
channels can be assumed. Moreover, the transmission of artificial noise can
lead to an increased electromagnetic field (EMF) exposure, which depends on the
considered location and can thus also be seen as a random variable. Hence, we
optimize the $\varepsilon$-outage secrecy rate under a $\delta$-outage exposure
constraint in a setup, where the base station (BS) is communicating to a user
equipment (UE), while a single-antenna eavesdropper with Rayleigh distributed
channels is present. Therefore, we calculate the secrecy outage probability
(SOP) in closed-form. Based on this, we convexify the optimization problem and
optimize the $\varepsilon$-outage secrecy rate iteratively. Numerical results
show that for a moderate exposure constraint, artificial noise from the BS has
a relatively large impact due to beamforming, while for a strict exposure
constraint artificial noise from the UE is more important.
