This paper focuses on network access security of mobile Internet, introduces security threats and challenges with which mobile Internet is confronted, analyzes its network architectures and interface proto-cols, presents cross-network unified authentication and authorization technique, and then describes net-work access security requirements. Regarding to EAP-SIM and EAP-AKA security mechanisms, this pa-per investigates the processes of network access authentication and key agreement, as well as every network element and equipment's function in the evolved packet core networks. It is hoped that this study will give protection for authentication, confidentiality, and integrality between user equipment and access network. It also provides available references to building security protection mechanism of mobile Internet.
