Security Threats and Security Issues in 4G Wireless Network

Examining Security Threats and Issues in 4G Wireless Networks

Abstract

4G is the next generation of wireless networks that will totally replace 3G networks. It will provide better speed data and streamed multimedia services to users on “Anytime, Anywhere" basis. The important and challenging issue in 4G is seamless handoff, mobility management, security and service between different integrated networks.This paper surveys security requirements, challenges, security threats and different 4G networks security architectures. It also discusses 4G security techniques and security issues. Specifically we discuss about Y-Comm security models for heterogeneous networks, Hokey Project, and ITU X.805 framework. It also describes security issues with physical layer, MAC layer, Key Management pertaining to integrated WiMax, WiFi, and 3G LTE networks.Our survey shows that a number of new security threats to cause unexpected service interruption and disclosure of information. We also found still there are several open security issues and challenges although many are working on fixing and designing new security architectures for 4G.and fully IP based multimedia services. 4G is all about an integrated, global network that will provide voice,
