A Comprehensive Analysis of Security Mechanisms in 5G Communication Systems

Wireless communication systems have been at risk of security attacks right from the very beginning. The first-generation wireless networks saw mobile phones and wireless channels as targets for illegal cloning and masquerading. The second generation of wireless networks was characterized by message spamming that became common not only for pervasive attacks but also injecting false information or broadcasting unwanted marketing information.Almost every security threat in 5G networks uses LTE weaknesses as a loophole. Some of them are illegal data consumption, target-type network device denial of service (DoS), information leaks, and audio eavesdropping. The various schemes to improve security of 5G network is proposed in the previous years. In this paper, various many techniques are analysed which in terms of certain parameters which can improve security of 5 G network.
