Over-the-air computation has the potential to increase the
communication-efficiency of data-dependent distributed wireless systems, but is
vulnerable to eavesdropping. We consider over-the-air computation over
block-fading additive white Gaussian noise channels in the presence of a
passive eavesdropper. The goal is to design a secure over-the-air computation
scheme. We propose a scheme that achieves MSE-security against the eavesdropper
by employing zero-forced artificial noise, while keeping the distortion at the
legitimate receiver small. In contrast to former approaches, the security does
not …
