A Secure Anonymous Identity-Based Scheme in New Authentication Architecture for Mobile Edge Computing

Abstract

Mobile edge computing (MEC) provides computing and data storage capabilities within the range of the wireless access network close to the users, which is driving the need for new type of security technologies. Faced with rapid traffic growth and increasing user experience requirements, the existing security schemes can no longer meet the new requirements of real time and lightweight. New solutions that do not require complex calculations, such as identity-based cryptography, attract great attention from researchers. To meet these demands, we design a new authentication architecture for MEC environment, which provides secure and efficient communication. Based on this authentication architecture, an anonymous identity-based scheme is proposed for lightweight devices. In the meantime, user anonymity is also fully protected. The proposed scheme is proved to be secure under a specific security model. In addition, we describe the security properties our scheme meets. The comparisons of time consumption and communicational cost are given at the end of the article, to demonstrate that our scheme performs prior to several previous schemes.
