PPSE: Privacy Preservation and Security Efficient AKA Protocol for 5G Communication Networks

摘要

The authentication and key agreement (AKA) protocol strengthens the security of mobile communication networks. The 5G-AKA protocol is standardized by the 3rd generation partnership project (3GPP) for future mobile communication networks. However, it is observed that this protocol is vulnerable to numerous security weaknesses. Moreover, the protocol suffers from huge computation and communication overhead. To overcome these issues, several AKA protocols were introduced by the researchers. However, none of the protocols took care of the identity preservation and single key disclosure issue over the communication channel. In this article, we propose the Privacy Preservation and Security Efficient (PPSE-AKA) protocol that preserves the user’s identity and protects the shared secret key. The mutual authentication is formally verified by using the AVISPA tool. The security analysis demonstrates that the protocol fulfills all the privacy requirements and dodges the potential attacks. The performance of the protocol is evaluated for the previously established schemes and observed that the PPSE-AKA protocol exhibits a cutting edge competition to them.
