We investigate the physical layer security of wireless single-input single-output orthogonal-division multiplexing (OFDM) when a transmitter, which we refer to as Alice, sends her information to a receiver, which we refer to as Bob, in the presence of an eavesdropping node, Eve. To prevent information leakage, Alice sends an artificial-noise (AN) signal superimposed over her information signal. We investigate the impact of the channel delay spread, OFDM cyclic prefix, information/AN power… 
Securing SC-FDE Uplink Transmissions Using Temporal Artificial Noise under Three Detection Strategies
This paper investigates the physical-layer security of single-input single-output uplink single-carrier frequencydomain equalization (SC- FDE) and derives a closed-form expression for the average secrecy rate at high input SNR under the worse-case scenario when Eve performs ML detection.
A hybrid artificial-noise and secret-key scheme for securing OFDM transmissions in V2G networks
A three-level optimization procedure to increase the average secrecy rate of this wiretap channel by optimizing the transmit power allocation between the encrypted data symbols, unencrypted data symbols and the AN symbols is proposed.
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret Key Aided Schemes
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.
Novel Secret-Key-Assisted Schemes for Secure MISOME-OFDM Systems
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.
Artificial Noise-Aided Secure Relay Communication With Unknown Channel Knowledge of Eavesdropper
Simulation results show that for most cases, secure communication can be achieved without the CSI knowledge of eavesdropper’s channels, and the achievable secrecy rate follows the trend of a benchmark system where the eavesdroppers’ full CSI is available.
The Secrecy Capacity Optimization Artificial Noise: A New Type of Artificial Noise for Secure Communication in MIMO System

Hybrid Spatio-Temporal Artificial Noise Design for Secure MIMOME-OFDM Systems
Artificial noise (AN) injection along the temporal and spatial dimensions of a legitimate system to secure its transmissions from potential eavesdropping is investigated and an upper bound on the secrecy rate loss due to the presence of the eavesdropper is derived.

This paper studies the use of artificial interference in reducing the likelihood that a message transmitted between two multi-antenna nodes is intercepted by an undetected eavesdropper, and uses the relative signal-to-interference-plus-noise-ratio (SINR) of a single transmitted data stream as a performance metric.

This paper investigates the power allocation problem for artificial noise (AN) secure precoding systems, and proposes closed-form solutions for maximizing the achievable secrecy rate, and shows that equal power and water-filling power allocations lead to similar solutions and rate loss.
Power Allocation and Time-Domain Artificial Noise Design for Wiretap OFDM with Discrete Inputs
A novel time-domain artificial noise design is proposed which exploits temporal degrees of freedom provided by the cyclic prefix of OFDM systems to jam the eavesdropper and boost the secrecy rate even with a single antenna at the transmitter.
Filter Design with Secrecy Constraints: The Degraded Parallel Gaussian Wiretap Channel
The design of transmit and receive filters that minimize the mean-squared error between the legitimate parties whilst guaranteeing a certain eavesdropper MSE level subject to a total average power constraint is considered.
Time-domain artificial noise generation technique using time-domain and frequency-domain processing for physical layer security in MIMO-OFDM systems
Time-domain time-domain AN generation techniques for MIMO orthogonal frequency division multiplexing (OFDM) systems are considered and the proposed technique achieves a higher secrecy rate when a MIMo-OFDM system is employed with the antenna configuration to which the conventional time- domain AN generation technique is hard to be applied.

This paper finds the trade-off curve between R and d, assuming essentially perfect (“error-free”) transmission, and implies that there exists a Cs > 0, such that reliable transmission at rates up to Cs is possible in approximately perfect secrecy.
