Distributed Security Architecture for Authentication in 4G Networks

4G network is the highly advanced wireless network which aids broadband as well as multimedia applications. 4G uses the TCP/IP architecture as the network backbone with open interfaces, which makes it susceptible to various network security risks. The increased set of features available at the user terminal also leads to the maximization of the security risks in 4G network. Hence, to overcome the security problems in the 4G network, in this paper we propose to develop distributed security architecture for authentication. In this proposed architecture, the Elliptic Curve Diffie-Hellman (ECDH) protocol is used for authenticating the mobile nodes within the network through hop by hop authentication and neighbor authentication.
