Enhanced physical layer security by OFDM signal transmission in fractional Fourier domains
(Institute of Electrical and Electronics Engineers, 2015)
The main idea of physical layer security for wireless communications is making the transmitted signal as meaningless for eavesdroppers. It can be achieved by signal processing techniques. In this study, fractional Fourier ...
Cyclic feature suppression for physical layer security
(Elsevier Sciences Bv, 2017)
Cyclic prefix (CP) deploying techniques such as orthogonal frequency division multiplexing (OFDM) and single carrier frequency domain equalization (SC-FDE) offer considerable advantages in terms of equalizing time dispersive ...
New physical layer key generation dimensions: Subcarrier indices/positions-based key generation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this letter, novel algorithms for secret key generation from the wireless channel in multi-carrier systems are proposed for ensuring the confidentiality and authentication in wireless communication systems. The novelty ...
Classifications and applications of physical layer security techniques for confidentiality: A comprehensive survey
(IEEE-Inst Electrical Electronics Engineers Inc, 2019)
Physical layer security (PLS) has emerged as a new concept and powerful alternative that can complement and may even replace encryption-based approaches, which entail many hurdles and practical problems for future wireless ...
Channel randomness-based adaptive cyclic prefix selection for secure OFDM system
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
A novel method for cyclic prefix (CP) adaptation based on wireless channel randomness is proposed for orthogonal frequency-division multiplexing (OFDM) systems in urban areas. Especially, a quantization algorithm and an ...
