A robust 4G/LTE network authentication for realization of flexible and robust security scheme

4G wireless communication allows for significant increases in data rates over 2G and 3g and 3.5G wireless technologies. 4G is based on TCP/IP architecture and thus by moving to an anticipated increase in security issues compared to previous generations. LTE is composed with cryptographic strategies, common verification between LTE network elements with wellbeing components incorporated with its building design. Be that as it may, the organizations and well known industries have distinguished security vulnerabilities that ought to be assessed by under network deployment. With the development of open, all IP-based, disseminated architecture of LTE, attackers can target versatile and systems with spam, tuning in, malware, IP spoofing, data and service theft, DDoS assaults numerous different varieties of digital attacks and crimes. Security issues and challenges in wireless networks remain a hotly debated issue later on, LTE/SAE standard could adjust to these difficulties upward, turning out to be more strong and secure. Looking verification calculations and ciphering as EAP-AKA (extensible authentication protocol for confirmation and key assention), as of now working inside of the LTE convention, the authors analyze vulnerabilities several LTE/SAE security architecture — especially, insecure AKA key derivation procedures and absence of quick reauthentications for handovers. The progressive structural planning of the present day networks cell information implies that countless stations rely on upon a little number of core network elements for vital administrations (counting internet availability). In this paper we have proposed an effective improvement in existing security method to make it capable of protecting the selective jamming, in order to address multiple nodes attempting to join the network at the same time i.e. Distributed Denial of Service (DDoS) attack. The existing protocol will be improved to protect against selective jamming attack in order to multiple nodes, a specific and severe DDoS attack.
