We propose a new scheme to enhance the physical-layer security of wireless single-input single-output orthogonal-frequency division-multiplexing (OFDM) transmissions from an electric vehicle, Alice, to the aggregator, Bob, in the presence of an eavesdropper, Eve. To prevent information leakage to Eve, Alice exploits the wireless channel randomness to extract secret key symbols that are used to encrypt some data symbols which are then multiplexed in the frequency domain with the remaining… 
Novel Secret-Key-Assisted Schemes for Secure MISOME-OFDM Systems
TLDR
Numerical results validate the theoretical findings and quantify the impact of different system design parameters for a new secure transmission scheme for uplink multiple-input single-output (MISO) orthogonal-frequency multiplexing (OFDM) systems in the presence of multiple eavesdroppers.

TLDR
It is proved that the number of useful AN streams that can degrade Eve’s signal-to-noise ratio is dependent on the channel memories of Alices–Bob and Alice–Eve links, and a hybrid security scheme is proposed that integrates temporal AN with channel-based secret key extraction.
