The exponentially increasing number of ubiquitous wireless devices connected\nto the Internet in Internet of Things (IoT) networks highlights the need for a\nnew paradigm of data flow management in such large-scale networks under\nsoftware defined wireless networking (SDWN). The limited power and computation\ncapability available at IoT devices as well as the centralized management and\ndecision-making approach in SDWN introduce a whole new set of security threats\nto the networks. In particular, the authentication mechanism between the\ncontrollers and the forwarding devices in SDWNs is a key challenge from both\nsecrecy and integrity aspects. Conventional authentication protocols based on\npublic key infrastructure (PKI) are no longer sufficient for these networks\nconsidering the large-scale and heterogeneity nature of the networks as well as\ntheir deployment cost, and security vulnerabilities due to key distribution and\nstorage. We propose a novel security protocol based on physical unclonable\nfunctions (PUFs) known as hardware security primitives to enhance the\nauthentication security in SDWNs. In this approach, digital PUFs are developed\nusing the inherent randomness of the nanomaterials of Resistive Random Access\nMemory (ReRAM) that are embedded in most IoT devices to enable a secure\nauthentication and access control in these networks. These PUFs are developed\nbased on a novel approach of multi-states, in which the natural drifts due to\nthe physical variations in the environment are predicted to reduce the\npotential errors in challenge-response pairs of PUFs being tested in different\nsituations. We also proposed a PUF-based PKI protocol to secure the controller\nin SDWNs. The performance of the developed ReRAM-based PUFs are evaluated in\nthe experimental results.\n
