A Comprehensive Survey of the 6G Network Technologies

Currently, with the evolution of technology, 5G has become an efficient tool in terms of communication with high speed and less latency. Nevertheless, 5G implementation is still taking place and the whole world seems to be already talking about what might appear next – 6G. In the field of network technology, with the launch of 6G network set in 2030, it targets to resolve the restrictions of existing 5G technology and offer its users even better services than ever before. But like any other technological development, the 6G network is supposed to be a bloom filled with security challenges and issues. This survey is important because it provides a comprehensive insight into the security needs, problems, attacks and solutions of 6G networks. This survey starts with a reference over the former technologies, and specifies the 6G technology trends of today, illustrating the typical technologies in addition to their security challenges by each aspect. It also discusses certain physical-layer-specific security concerns and challenges that the current literature has yet to address, which is very necessary for researchers who are delving into 6G network security. In this way, we can anticipate and devise strategies for the safety and security of 6G networks. Finally, the full consideration of 6G technologies is also provided in this survey that anyone working on this upcoming technology should know.
