We propose Authentication and Key Agreement (AKA) for Machine Type Communications (MTC) in LTEAdvanced. This protocol is based on an idea of grouping devices so that it would reduce signaling congestion in the access network and overload on the single authentication server. We verified that this protocol is designed to be secure against many attacks by using a software verification tool. Furthermore, performance evaluation suggests that this protocol is efficient with respect to authentication overhead and handover delay. I. INTRODUCTIONThe Machine Type Communications (MTC) enables millions of MTC devices to communicate with each other [1]. We expect that this new technology will realize new applications that are not feasible through human-to-human (H2H) communication. We propose, as part of a security remedy, a group-based authentication and key agreement that operates by leveraging group information to authenticate a number of devices in a group efficiently and effectively without any needs of excessive authentication signaling.
