Security Enhanced Authentication and Key Agreement Protocol in Next Generation Mobile Network
The 3rd Generation Partnership Project (3GPP) standard is developing System Architecture Evolution (SAE)/Long Term Evolution (LTE) for the next generation mobile communication system. In the SAE/LTE architecture, EPS AKA (Evolved Packet System Authentication and Key Agreement) procedure is used to provide mutual authentication between the UE (User Equipment) and the serving network. However the EPS AKA has several vulnerabilities such as disclosure of user identity, man-in-middle attack, etc. Therefore, this paper analyzes the deficiencies of the EPS AKA, and proposes a Security Enhanced Authentication and Key Agreement (SE-EPS AKA) based on Wireless Public Key Infrastructure (WPKI).
