“…Rather than replacing cryptography at higher layers, one of PLE's benefits is to enable using lightweight cryptosystems, an important issue in devices with limited resources. Researchers considered PLE in a variety of communication systems including OFDM systems [11], [12], massive MIMO systems [13]- [15], Untrusted Relaying Systems [16], IEEE 802.15.4 protocols [17], rateless codes [18] and sparse code multiple access (SCMA) [19]. The work in [17] implemented a PLE system in ASIC and FPGA with low complexity and latency.…”

Security is always an important issue in wireless communications. Physical layer encryption (PLE) is an effective way to enhance wireless communication security and prevent eavesdropping. Rather than replacing cryptography at higher layers, PLE's benefit is to enable using lightweight cryptosystems or provide enhanced security at the signal level. The upper cryptography is faced with a noise-free channel, and the processing object is bit data. In PLE, the effects of channel and noise can be exploited to enhance security and prevent deciphering. In addition, since the processing object is complex vector signals, there are more operational functions to select and design for PLE. The mathematical models, design frameworks, and cryptographic primitives of PLE are established. Two design frameworks are proposed: stream PLE and block PLE. For stream PLE, a new 3D security constellation mapping is derived. For block PLE, two types of sub-transforms are defined: isometry transformations and stochastic transformations. Furthermore, a practical system operation mode PLE-block chaining (PBC) is proposed to enhance the practical system security. The proposed PLE framework can resist known plaintext attacks and chosen-plaintext attacks. The simulation shows that the proposed isometry transformation method has good performances in terms of bit error ratio (BER) penalty and confusion degree.

“…Moreover, as the development of supercomputer, the traditional encryption techniques based on high calculated amounts are hard to satisfy the requirements of security. Against the background, as an important part of information‐theoretic security, physical layer security (PLS) [6] techniques have been proposed to exploit the feature of wireless communications to enhance the security such as security coding [7, 8], cooperative interference [9, 10] and key generation [11, 12].…”

“…Wireless physical layer security (PLS) [8] makes full use of the characteristics of channels in the wireless physical layer and both legitimate communication parties can recover the original information, while eavesdroppers (Eve) can not obtain secret information. Generally, PLS mainly includes security coding [9]- [11], cooperative interference [12], [13] and key generation [14]- [16]. Polar codes have excellent performance and special constructions due to their nested codeword structure [17] which can realize random binning [18] in PLS coding.…”

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.
