Hierarchical Access Control for SDP-IoT

In this paper, we describe how to apply the SDP protocol to IoT networks (let's refer to it as SDP-IoT) to defend against DDoS(Distributed Denial of Service) attacks, one of the biggest security issues in IoT networks. However, in SDP-IoT, since the control server manages all devices connected to the network, invasion of privacy and big brother problems may occur. In order to solve it, this paper proposes a hierarchical access control method and proposes a method to apply it to SDP-IoT.
