Design and Performance Analysis of Sensor Proxy-AAA Authentication Scheme Based on Fast Handover and Forwarding Mode for IP-based Internet of Things

Recen tly interest in Internet of Things(I oT) is increasing, and a variety of the security technol ogies tha t are suitable for Internet of Things has being studied. In order to main tain the trustw orth y connectivity and the accessibility of distributed IoT, it is importan t to establish secure links for endto-end comm unica tion with proper authen tica tion. AAA technol ogy is curren tly the best way of resol ving dela y issue when introd ucing authen tica tion process of mobile switching. How ever, there are still a number of issues among which the dela y time issue from authen tica tion and authoriza tion grea tly inf uences the process. AAA applica tion in mobile IP environmen t cannot f uen tly support continuous and fast handov er in both intra-domain and inter-domain. Mobile IPv6 (MIPv6) is a host -based protocol supporting gl obal mobility . On the other hand, Proxy Mobile IPv6 (PMIPv6) is a netw ork-based protocol supporting localized mobility . This paper , the additional cost from combina tion of PMIPv6, authen tica tion, authoriza tion and accoun ting (AAA) and the way of red ucing extended dela y time will be explained. First , a new authen tica tion scheme (Proxy -AAA) is proposed tha t supports forw arding mode and fast handov er mode betw een other local mobility anchors (LMAs). Second, configur cost anal ysis model based on Proxy -AAA. Based on theoretical anal ysis, it was confirme tha t the cost is affected by average arriv al rate and residence time.
