A Multi-Server Authentication Protocol Achieving Privacy Protection and Traceability for 5G Mobile Edge Computing

摘要

Mobile Edge Computing (MEC) is placed near mobile devices in the form of edge servers to meet the requirements of time-sensitive applications, providing low-latency computing and data storage. As user privacy issues are considered one of the biggest issues in the MEC environment, there are various approaches for anonymous authentication. However, these are not ready for commercial applications due to a lack of user traceability for rewards, service fees, penalties, and so on. This paper proposes a user authentication protocol in the MEC environment that satisfied the two conflicting security requirements of user anonymity and traceability. The proposed protocol provides anonymous mutual authentication between mobile devices and application servers operating on MEC platform, while ensures that the trusted MEC server can securely track users on behalf of service providers.
