Physical Layer Security Analysis of Cognitive NOMA Internet of Things Networks

The Security of Physical Layer in Cognitive Radio Networks

—Cognitive Radio (CR) is a novel technology that promises to solve the lack of spectrum by allowing secondary users to use licensed band, so that they can coexist with primary users without causing interference to their communications. With the development of CR, extending to the level of network, cognitive radio networks (CRNs) emerge as the times require. Nowadays the operational aspects of ...

Synopsis of Research Problem Wireless Physical Layer Security for Internet of Things (IoT) Applications

Wireless communication is one of the key technologies that actualize the Internet of Things (IoT) concept into the real world [1]. The foundation of the security management of IoT is laid by understanding the security performance of wireless communication. The term IoT is synonymous with the cyber–physical system, or a ‘‘network of networks’’ [2], where a variety of things (like sensors, mobile...

Integrating Wireless Sensor Networks into Internet Of Things For Security

A secure channel between a sensor node and internet host is created, hence new security challenges arises and wireless sensor networks is integrated into internet of things. We use heterogeneous online/offline signcryption scheme so that secure communication is provided. We use bilinear diffie-hellman inversion problem in random oracle model, it provides indistinguishability against adaptive ch...

Low Power Link Layer Security for Internet of Things: Implementation and Performance Analysis

In this paper we present the implementation and performance evaluation of security functionalities at the link layer of IEEE 802.15.4-compliant IoT devices. Specifically, we implement the required encryption and authentication mechanisms entirely in software and as well exploit the hardware ciphers that are made available by our IoT platform. Moreover, we present quantitative results on the mem...
