An Efficient Anonymous Authentication Scheme to Improve Security and Privacy in SDN Based Wireless Sensor Networks

Abstract

Nowadays, software defined networking (SDN) model can sustain potentially support and flexible routing in various communication patterns that occur in wireless sensor networks (WSN). But implementing this model to resource-constrained networks is not direct, particularly if security services are an essential. For WSN existing SDN-based approaches developed addressing resource-constrained requirements and over time. Still in their implementation and design they do not integrate security services. In this paper we propose, an efficient anonymous authentication scheme to enhance security and privacy in SDN based WSN (SDWSN). The proposed method has perfect forward secrecy, achieve user anonymity and at the same time resistance to attack. For the resource constrained sensor nodes, it is very suitable. Also, a secure and efficient protocol for SDWSN is designed to detect and prevent security threads like flooding, replay and poison attacks which is due to lack of source authentication. Experimental results show the efficiency and effectiveness of proposed method in terms of delay, energy consumption, throughput, Packet Delivery Ratio (PDR) and packet loss. The proposed method is implemented utilizing NS-2 simulation and compared with existing protocol named lightweight anonymous authentication protocol (LAAP) and demonstrates our proposed method works better.

Introduction Wireless Sensor Networks (WSN) is made out of resource constrained devices, from the environment with the motivation behind data gathering [1][2][3]. About the world, these devices can process, communicate and sense, perception and increment data. In WSN there are numerous applications, in which information source authentication, integrity and information confidentiality are the vital security services. The conventional networks security mechanisms can cause unwanted impacts like increment in communication delay/energy consumption from the processing overhead. For the execution of security mechanisms in WSN one of the fundamental difficulties is to illuminate the conflict between maximizing security and minimizing resource consumption [1,5]. In correspondence protocols deployment moreover attributes like heterogeneity and mobility present new difficulties. For WSN routing protocols advanced over time. For example, in occasion and intrigue based networks coordinated diffusion was structured [6], exclusive traffic pattern of CTP (Collection Tree Protocol) is satisfactory [7], and to address diverse routing patterns like communication of node-to-sink, sink-to-node and node-to-node Ten RPL (RFC6550) was presented [8]. In any case, in node to-sink traffic it is intended to be proficient. The security services arrangement and routing flexibility issues can potentially be tended to by the supposed SDN [9, 10], a worldview to control the network conduct that utilizes logically centralized software. For the SDN southbound protoc...
