Protocol Security in 6th Generation (6G) Networks

6th generation networks are expected to be there most probably in year 2030. It is believed that their existence will enable the technology of Internet of Everything. People are already using the 5G Networks and facing several issues in that due to which the 6G networks are very important to develop. 6G technology ensures to connect every device present in the world with the internet providing Quality of Service. The 6G networks are still in discussion stage and it is identified that there is need of tackling the several issues related to security and implementation to get better and secure services from 6G Network. A lot of research is being carried out to ensure the security and integrity of 6G Technology. Various issues need to be addressed before implementing 6G Networks. The security is the main aspect behind the 6G Networks so security must be ensured at each layer of network model. The protocol security is very crucial issue to be considered. In this article, the security is the major concern that has been discussed in detail. Very few researchers have done the work on 6G protocol security in last three years. So, in this article, the main focus is to explore the security protocols and the issues related with the protocols to provide 6G network security have been elaborated to provide the way to the researchers to explore and resolve the 6G Security protocols. The future issues and challenges that need to be focused have also been discussed in this work.
