We propose Authentication and Key Agreement (AKA) for Machine Type Communications (MTC) in LTE-Advanced. 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(More)
Machine type communication (MTC) takes advantages of billions of devices being connected to each other in sensing our ambient environments. When a large number of MTC devices in a group attempt to access a radio link of LTE, congestions in the link may drop throughput of data and signaling traffic significantly. This paper is presented to enhance security(More)
