A Provably Secure and Efficient Identity-Based Anonymous Authentication Scheme for Mobile Edge Computing

Mobile edge computing (MEC) allows one to overcome a number of limitations inherent in cloud computing, although achieving the broad range of security requirements in MEC settings remains challenging. In this paper, we focus on achieving mutual authentication with anonymity and un-traceability, as this is crucial in ensuring data security and user privacy. Specifically, we design an identity-based anonymous authenticated key agreement protocol for the MEC environment. The proposed protocol achieves mutual authentication in only a single message exchange round, as well as assures both user anonymity and un-traceability. We then evaluate the security and performance of the protocol, and demonstrate that it achieves the required security properties and outperforms prior approaches in terms of communicational and computational costs.
