A review on security aspects in 5G systems: VLSI perspective

In the present scenario, security is the prime requirement because of the increasing usage of the internet or public cloud for storing the data. It aims at preserving the integrity, confidentiality, availability of the information system resources. The trend towards ubiquitous computing environment can be envisioned by addressing the 5G system. On one hand, the integration of multiple existing progressive technologies can target the objective, but, may lead to vast security challenges in the future 5G mobile networks. Nowadays, security in the public environment is necessary for preserving the data secrecy. The available private environments are more expensive than public area. As a result, everyone is agreeable with internet i.e. public cloud. Though several cryptographic techniques are proposed in Very Large Scale Integration with the consideration in area, power and speed. This paper concentrates on the survey of various cryptographic algorithms for existing systems of 3G, 4G and analyze the necessity for additional security aspects for 5G and suggests the choice of the encryption scheme that fits in the 5G pack to improve its performance.
