An IPv6-Based Distributed Source Address Validation Scheme in Internet of Things

Abstract

Under the background of Next-Generation of Internet based on the Internet of Things(IoT),an architecture of IP source address validation is proposed in this paper.Considering the resource-restraint of IoT nodes,the distributed IPv6 source address validation scheme is designed according to this architecture as well as the topology and routing manner in end-edge network of IoT.Meanwhile,IPv6 address allocation methods for IoT nodes and their authentication mechanisms are respectively discussed under the scenarios of static assignation,DHCPv6,SLAAC and DHCPv6-SLAAC mixed.The simulation has proved that our scheme can not only implement IP address allocation,but also keep the IP address authenticity with slight cost among IoT nodes,as well as between IoT nodes and Internet end-host.As a result,the whole security in IoT is enhanced.
