Researches on 5th generation mobile communication networks (5G) are emerging to meet the demands of rapidly developing communications applications. The reliability and security of data have become key factors of its development, and thus 5G has put forward higher requirements for new coding and encryption technologies. In this paper, a physical layer encryption algorithm based on polarization codes and chaotic sequences is proposed to improve the reliability and confidentiality of transmission. In our scheme, chaotic sequences are allocated in the frozen bits of polar codes. Therefore, error correction and encryption can be performed simultaneously. Since the frozen bits are unknown to the eavesdroppers, it is difficult for them to decode the transmitted bits without the knowledge of the chaotic sequences. To further improve the security, we propose to generate the chaotic sequences by using the channel state information. Besides, the chain effects of delayed feedback are applied to increase the decrypted complexity of the eavesdroppers in this paper. Theoretic analysis and simulation results both show that the proposed algorithms can achieve high security without any error rate performance loss.

“…However, a recent study has shown that such pencil-sharp beams are still vulnerable to agile eavesdropping [72]. Other physical layer encryption algorithms, including source coding approaches such as the low-density parity-check (LDPC) code, are demonstrated with optimal performance under specific conditions [73]. Furthermore, existing solutions in the reconfigurable intelligence surface apply reflectarrays, which do not have the capability to effectively distinguish target users from malicious attackers.…”

The next generation of wireless communication networks, or 6G, will fulfill the requirements of a fully connected world and provide ubiquitous wireless connectivity for all. Transformative solutions are expected to drive the surge for accommodating a rapidly growing number of intelligent devices and services. Major technological breakthroughs to achieve connectivity goals within 6G include: (i) a network operating at the THz band with much wider spectrum resources, (ii) intelligent communication environments that enable a wireless propagation environment with active signal transmission and reception, (iii) pervasive artificial intelligence, (iv) large-scale network automation, (v) an all-spectrum reconfigurable front-end for dynamic spectrum access, (vi) ambient backscatter communications for energy savings, (vii) the Internet of Space Things enabled by CubeSats and UAVs, and (viii) cell-free massive MIMO communication networks. In this roadmap paper, use cases for these enabling techniques as well as recent advancements on related topics are highlighted, and open problems with possible solutions are discussed, followed by a development timeline outlining the worldwide efforts in the realization of 6G. Going beyond 6G, promising early-stage technologies such as the Internet of NanoThings, the Internet of BioNanoThings, and quantum communications, which are expected to have a far-reaching impact on wireless communications, have also been discussed at length in this paper.

Advance communication systems such as fifth generation (5G) and 5G+ expect to deploy the security solutions for securing the communication networks. Finding the optimum size of the security gap is a challenging problem in the large scale networks. In this paper, the parity check matrix (H) of low-density parity check (LDPC) considered for determining the security gap is analyzed with the higher rate LDPC coding schemes and different size of frames. Here, optimum LDPC decoding is considered as a method. Especially, the physical layer is investigated with H and two different high-rate codes and simulated to find the optimum size of security gaps for better security. Also, non-orthogonal multiple access (NOMA) is employed to enhance the security solution. Thus, optimum security gap is possible when suitable NOMA is employed in the physical layer of the 5G communication system. As expected in this research conclusion, simulation results show that the security gap decreases when frame size is increased. General TermsIn this paper, the design of the security gap in the 5G communication channel is considered. Throughout this research, LDPC and NOMA provide optimum security for improving the physical layer of the 5G communication.
