摘要: The 4th generation (4G) mobile access network and the core are evolving towards a secure, fast, Internet Protocol-based network. With emergence of next battery-powered smart phone open source application platforms, security terminal's energy consumption have become big issues. Long Term Evolution (LTE) is one most popular 4G technologies defined by 3rd Generation Partnership Projects (3GPP). It observed that end user requires two authentication steps to multimedia services. first LTE layer authentication, second IP Multimedia Subsystem (IMS) service authentication. utilize carried out using Authentication Key Agreement (AKA) protocol. This paper proposes an Improved AKA (I-AKA) protocol which authenticates on both without double execution simplifies steps. Furthermore, were analyzed results showed proposed I-AKA could save up 81.82% related with increased security.
