“…However, the boosting wireless connections, the prosperity of various delay-sensitive traffics as well as limitations of end-devices in energy, processing capability, storage, and hardware in 6G require more efficient and low-cost solutions for the security and privacy. Lightweight and flexible solutions such as group-based authentication and anonymous service-oriented authentication strategies [414,415] will be the main research and development direction of the cryptography-based security and privacy.…”

The fifth generation (5G) wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability, and guaranteed low latency. However, 5G will not meet all requirements of the future in 2030 and beyond, and sixth generation (6G) wireless communication networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, better intelligence level and security, etc. To meet these requirements, 6G networks will rely on new enabling technologies, i.e., air interface and transmission technologies and novel network architecture, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing. Our vision on 6G is that it will have four new paradigm shifts. First, to satisfy the requirement of global coverage, 6G will not be limited to terrestrial communication networks, which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle (UAV) communication networks, thus achieving a space-air-ground-sea integrated communication network. Second, all spectra will be fully explored to further increase data rates and connection density, including the sub-6 GHz, millimeter wave (mmWave), terahertz (THz), and optical frequency bands. Third, facing the big datasets generated by the use of extremely heterogeneous networks, diverse communication scenarios, large numbers of antennas, wide bandwidths, and new service requirements, 6G networks will enable a new range of smart applications with the aid of artificial intelligence (AI) and big data technologies. Fourth, network security will have to be strengthened when developing 6G networks. This article provides a comprehensive survey of recent advances and future trends in these four aspects. Clearly, 6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.

“…It is foreseen from the features of 6G-enabled IoT communications [23]- [25] that, RA procedure is one of the most frequently used and energy consuming operations in devices. As the foremost step in RA procedure, an appropriate design and effective detection of RA preamble can remarkably enhance the success probability of first access, and is consequently conducive to reducing both the energy consumption and average access delay, so as to improve the access efficiency for massive IoT devices.…”

Satellite communication system is expected to play a vital role for realizing various remote internet of things (IoT) applications in 6G vision. Due to unique characteristics of satellite environment, one of the main challenges in this system is to accommodate massive random access (RA) requests of IoT devices while minimizing their energy consumptions. In this paper, we focus on the reliable design and detection of RA preamble to effectively enhance the access efficiency in highdynamic low-earth-orbit (LEO) scenarios. To avoid additional signaling overhead and detection process, a long preamble sequence is constructed by concatenating the conjugated and circularly shifted replicas of a single root Zadoff-Chu (ZC) sequence in RA procedure. Moreover, we propose a novel impulse-like timing metric based on length-alterable differential cross-correlation (LDCC), that is immune to carrier frequency offset (CFO) and capable of mitigating the impact of noise on timing estimation. Statistical analysis of the proposed metric reveals that increasing correlation length can obviously promote the output signal-to-noise power ratio, and the first-path detection threshold is independent of noise statistics. Simulation results in different LEO scenarios validate the robustness of the proposed method to severe channel distortion, and show that our method can achieve significant performance enhancement in terms of timing estimation accuracy, success probability of first access, and mean normalized access energy, compared with the existing RA methods.

“…Networking patterns of 6G networks are outlined in [22]- [24], in which cell-less architecture, decentralized resource allocation, and three-dimensional super-connectivity are highly expected to exist in 6G networks. MTCs and vertical-specific wireless network solutions for 6G are studied in [25], which believes that 6G would facilitate the first wall-breaking standard to completely replace existing industry-specific communication standards and provide a unified solution enabling seamless connectivity for all needs in vertical industries.…”

“…3) Secure Ultra-Reliable Low-Latency Communications (SURLLC): The SURLLC in 6G is a joint upgrade of the URLLC and the mMTC in 5G, but with higher requirements of reliability (higher than 99.9999999%, i.e., 'Seven Sigma' from the viewpoints of quality control and process improvement) and latency (less than 0.1 ms) [25], as well as an additional demand on security. The SURLLC mainly serves the industrial and military communications, e.g., a variety of robots, highprecision machine tools, and conveyor systems in the 6G era.…”

<pre>As the standardization of fifth generation (5G) communications has been completed, and the 5G network will be commercially launched in 2020, the research visioning and planning of sixth generation (6G) communications are being initiated. 6G communications are expected to be the next focus in wireless communication and networking and aim to provide remarkable communication services to meet the future demands in the 2030s. We believe that the human-centric mobile communications will still be the most important application of 6G and 6G network should be human-centric. Following this rationale, high security, secrecy, and privacy are the all-important features of 6G, which shall be paid special attention from the wireless research community. To promote the research and the human-centric design ideology for 6G communications, we imagine in this article a comprehensive and systematic framework of 6G with five slices, key features, and enabling technologies. Furthermore, we briefly discuss the issues of 6G beyond communication technologies. Overall, the article aims to provide an envisioned picture of 6G and serve as a research guideline in the post-5G era.</pre>
