Extended Authentication and Key Agreement Protocol of UMTS

Abstract
Identification, authentication and key agreement protocol of UMTS networks have some weaknesses to provide DoS-attack resistance, mutual freshness, and efficient bandwidth consumption. In this article we consider UMTS AKA and some other proposed schemes. Then we explain the known weaknesses in the previous frameworks suggested for UMTS AKA protocol. After that we propose a new UMTS AKA protocol (called EAKAP) for UMTS mobile network that combines identification stage and AKA stage of UMTS AKA protocol as well as eliminating disadvantages of related works and bringing some new features to improve the UMTS AKA mechanism such as reducing the interactive rounds of the UMTS AKA protocol.
