Security Enhanced Authentication and Key Agreement Protocol in Next Generation Mobile Network
نویسنده
چکیده
The 3 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-inmiddle 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). Then, the new SE-EPS AKA has been proved with the formal verification method, and the proof result shows that the SE-EPS AKA can satisfy the security and efficiency properties in the SAE/LTE architecture.
