“…In [23], a concatenated coding scheme combining polar codes and fountain codes is proposed by Yang and Zhuang for memoryless erasure binary eavesdropping channel models, while relying on finite code lengths for ensuring security. Hao et al [33] discuss a secure transmission scheme employing two-dimensional polar codes designed for block fading eavesdropping channels, in the face of instantaneous secrecy capacity fluctuations. Bao et al [24] combine polar codes with artificial noise to derive upper and lower bounds of the symmetric capacity for polarized bit channels, which benefit the legitimate receiver but not the eavesdropper.…”

A novel Physical Layer Security (PLS) framework is conceived for enhancing the security of the wireless communication systems by exploiting multi-domain polarization in Multiple-Input Multiple-Output (MIMO) systems. We design a sophisticated key generation scheme based on multi-domain polarization, and the corresponding receivers. An in-depth analysis of the system's secrecy rate is provided, demonstrating the confidentiality of our approach in the presence of eavesdroppers having strong computational capabilities. More explicitly, our simulation results and theoretical analysis corroborate the advantages of the proposed scheme in terms of its bit error rate (BER), block error rate (BLER), and maximum achievable secrecy rate. Our findings indicate that the innovative PLS framework effectively enhances the security and reliability of wireless communication systems. For instance, in a 4 × 4 MIMO setup, the proposed PLS strategy exhibits an improvement of 2dB compared to conventional MIMO, systems at a BLER of 2 • 10 −5 while the eavesdropper's BLER reaches 1.

“…Polar codes have excellent performance and special constructions due to their nested codeword structure [17] which can realize random binning [18] in PLS coding. Therefore, many scholars have applied polar codes to the model of wiretapping channel [19], [19]- [21], which promotes further development of PLS coding theory. Moreover, chaotic encryption is one of the important way to implement PLS.…”

Channel coding and security are important in a communication system. The 5th generation (5G) mobile communication networks call for higher requirements of new coding technologies and encryption technologies. As an efficient coding method, polar codes have attracted more attention in recent years. Besides, the peak-to-average-power ratio (PAPR) is a major problem of the orthogonal frequency-division multiplexing (OFDM) system, which will significantly affect the performance of the OFDM system. In this paper, joint physical-layer encryption and PAPR reduction scheme is proposed, aiming to solve the PAPR problem and achieve high security of the transmission system. In this scheme, we utilize the key generation technology of wireless channels to get the initial value of chaotic sequences. Then, the chaotic sequences can be used to encrypt the information and reduce PAPR simultaneously. Moreover, we use the best information bits of polar codes to store the serial number index of chaotic sequences. The theoretic analysis and simulation results show that the proposed scheme can not only achieve high security in the physical layer but also reduce PAPR in the OFDM system without increasing system complexity and latency.
