doi:10.3969/j.issn.1671-1122.2021.11.007

Abstract

Abstract:

Mobile edge computing is a new computing paradigm, which can provide real-time computing, data optimization and smarter application to mobile smart devices by deploying mobile edge computing servers that are closer to the data sources. This paper focuses on the problem of secure identity authentication between mobile devices and mobile edge computing servers, and proposed a light-weight mutual authentication protocol for mobile edge computing based on elliptic curve cryptography and Hash function. The protocol achieved mutual authentication, mobile user anonymous protection and mobile user untraceability, and was secure against replay attack and man-in-the-middle attack. According to performance analysis and comparison with similar protocols, the proposed protocol has lower computational costs, and is suitable for resource constrained mobile smart devices.

Key words: Internet of things, edge computing, identity authentication, elliptic curve cryptography, privacy protection
