A localized authentication, authorization, and accounting (AAA) protocol for mobile hotspots

摘要: Mobile hotspots, i.e. Internet access services in moving networks (e.g. vehicular area (VAN) and personal (PAN)) bring about new challenging issues. Even if the network mobility (NEMO) basic support protocol has been standardized as a solution by Engineering Task Force (IETF), to best of our knowledge, no studies have conducted authentication, authorization, accounting (AAA) protocol, which is core technology for public mobile hotspots. In this paper, we propose localized AAA retain transparency NEMO reduce cost procedure. addition providing mutual proposed prevents various threats such replay attack, man middle key exposure. Also, develop an analytical model evalutate signaling cost. Numerical results reveal that suitable different
