Design and Simulation of New Anonymous Intelligent Authentication for 4G (LTE) Mobile Communication Network

Abstract

LTE becomes the most widely used mobile communication network and it covers 97% of U.S users. However, LTE security protocol fails to achieve full protection to LTE network. Therefore, LTE needs to provide more security for networks and users. In this paper, we analyze several attacks. First, Disclosure attack which is resulted from sending permanent International Mobile Subscriber Identity (IMSI) in plaintext and this is solved by using anonymous intelligent authentication second, the problem of using the User Equipment (UE) master key for all users which is used in the authentication standard protocol and this problem is solved using a new algorithm to derive a temporary key for each session. The proposed security architecture enhances the LTE security level.
