A New Authentication and Key Agreement Protocol for next Generation 3GPP Mobile Networks

Authentication is the act of proving the truthfulness of data or entity. But with respect to the protocol, authenticating a connection is the process of authenticating the mobile station with respect to its Network (SN) in mobile telecommunication system. The prime objective of this research paper is to propose an enhancement to UMTS AKA in order to remove the above defined redirection attack and make authentication in 3G networks more secure. The main contribution of this research paper is to define a secure authentication method for communication between Mobile Station (MS) and Home Network (HN) and preventing eavesdropping between MS and the Serving Network (SN). The proposed protocol can minimize number of flows and also it can reduce computational overheads to as much as possible. The simulation results indicate that proposed ELI-AKA protocol can more efficiently provide data security and reliability.
