Abstract
An apparatus includes a Base Station (BS) that includes an antenna array and circuitry. The antenna array is configured to transmit downlink transmissions and to receive uplink transmissions. The circuitry is configured to generate secret bits to be used for securing uplink transmissions from legitimate user devices, and to distribute the secret bits over one or more data streams destined to the legitimate user devices, to further generate one or more jamming streams, and to apply to the jamming streams beamforming that directs the jamming streams away from the legitimate user devices, to transmit the data streams and the jamming streams using the antenna array, to receive, via the antenna array, data that was encrypted by a legitimate user device based on the secret bits, and to recover the data by decoding the encrypted data using the secret bits.
