| Summary: | Recently interest in Internet of Things(IoT) is increasing, and a variety of the security technologies that are suitable for Internet of Things has being studied. In order to maintain the trustworthy connectivity and the accessibility of distributed IoT, it is important to establish secure links for end-to-end communication with proper authentication. AAA technology is currently the best way of resolving delay issue when introducing authentication process of mobile switching. However, there are still a number of issues among which the delay time issue from authentication and authorization greatly infuences the process. AAA application in mobile IP environment cannot fluently support continuous and fast handover in both intra-domain and inter-domain. Mobile IPv6 (MIPv6) is a host-based protocol supporting global mobility. On the other hand, Proxy Mobile IPv6 (PMIPv6) is a network-based protocol supporting localized mobility. This paper, the additional cost from combination of PMIPv6, authentication, authorization and accounting (AAA) and the way of reducing extended delay time will be explained. First, a new authenthication scheme (Proxy-AAA) is proposed that supports forwarding mode and fast handover mode between other local mobility anchors (LMAs). Second, configured cost analysis model based on Proxy-AAA. Based on theoretical analysis, it was confirmed that the cost is affected by average arrival rate and residence time.
