Machine To Machine (M2M) communications, also called Machine-Type Communications (MTC), has widely been utilized in applications such as telemetry, industrial, automation, and SCADA systems. The group-based MTC, especially when MTC devices belong to non-3GPP network, will face new challenge of access authentication. In this paper, the authors propose a group authentication and key agreement protocol, called EG-AKA, for machine-type communications combining Elliptic Curve Diffie-Hellman (ECDH) based on EAP framework. Compared with conventional EAP-AKA, their protocol guarantees stronger security and provides better performance.
