Available in PDF, EPUB and Kindle. Book excerpt: Wireless networks are built upon a shared medium that makes it easy for adversaries to conduct radio interference, or jamming attacks, which effectively cause a denial of service (DoS) of either transmission or reception functionalities. These attacks can be easily accomplished by an adversary by either bypassing MAC-layer protocols, or emitting a radio signal targeted at jamming a particular channel. In this thesis, we examine the issue of jamming wireless networks, and sensor networks in particular, by studying both the attack and defense side of the problem. On the attack side, we present four different jamming attack models that can be used by an adversary to disable the operation of a wireless network, and evaluate their effectiveness in terms of how each method affects the ability of a wireless node to send and receive packets. In order to cope with the problem of jamming, we discuss a two-phase strategy involving the diagnosis of the attack, followed by a suitable defense strategy. For detection, we show that single measurement statistics are not enough to reliably classify the presence of a jamming attack, and propose multimodal detection methods. To cope with jamming, we propose a technique, channel surfing, which involves evading the interferer in the spectral domain. Several different channel surfing models are presented, and we evaluate their effectiveness using a testbed of MICA2 motes. Beyond channel surfing, we overview a second defense strategy whereby it is possible to establish a low data rate jamming resistant communication channel by modulating the interarrival times between jammed packets.

Available in PDF, EPUB and Kindle. Book excerpt: Securing Emerging Wireless Systems: Lower-layer Approaches aims to fill a growing need in the research community for a reference that describes the lower-layer approaches as a foundation towards secure and reliable wireless systems. Whereas most of the references typically address cryptographic attacks by using conventional "network security" approches for securing wireless systems, the proposed book will be differentiated from the rest of the market by its focus on non-cryptographic attacks that cannot easily be addressed by using traditional methods, and further by presenting a collection of defense mechanisms that operate at the lower-layers of the protocol stack and can defend wireless systems before the effects of attacks propagate up to higher-level applications and services. The book will focus on fundamental security problems that involve properties unique to wireless systems, such as the characteristics of radio propagation, or the location of communicating entities, or the properties of the medium access control layer. Specifically, the book provides detection mechanisms and highlights defense strategies that cope with threats to wireless localization infrastructure, attacks on wireless networks that exploit entity identity (i.e. spoofing attacks), jamming and radio interference that can undermine the availability of wireless communications, and privacy threats where an adversary seeks to infer spatial and temporal contextual information surrounding wireless communications. Additionally, the authors explore new paradigms of physical layer security for wireless systems, which can support authentication and confidentiality services by exploiting fading properties unique to wireless communications.
Download or read book Embracing Interference in Wireless Systems written by Shyamnath Gollakota and published by Morgan & Claypool. This book was released on 2014-06-01 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wireless medium is a shared resource. If nearby devices transmit at the same time, their signals interfere, resulting in a collision. In traditional networks, collisions cause the loss of the transmitted information. For this reason, wireless networks have been designed with the assumption that interference is intrinsically harmful and must be avoided. This book, a revised version of the author's award-winning Ph.D. dissertation, takes an alternate approach: Instead of viewing interference as an inherently counterproductive phenomenon that should to be avoided, we design practical systems that transform interference into a harmless, and even a beneficial phenomenon. To achieve this goal, we consider how wireless signals interact when they interfere, and use this understanding in our system designs. Specifically, when interference occurs, the signals get mixed on the wireless medium. By understanding the parameters of this mixing, we can invert the mixing and decode the interfered packets; thus, making interference harmless. Furthermore, we can control this mixing process to create strategic interference that allow decodability at a particular receiver of interest, but prevent decodability at unintended receivers and adversaries. Hence, we can transform interference into a beneficial phenomenon that provides security. Building on this approach, we make four main contributions: We present the first WiFi receiver that can successfully reconstruct the transmitted information in the presence of packet collisions. Next, we introduce a WiFi receiver design that can decode in the presence of high-power cross-technology interference from devices like baby monitors, cordless phones, microwave ovens, or even unknown technologies. We then show how we can harness interference to improve security. In particular, we develop the first system that secures an insecure medical implant without any modification to the implant itself. Finally, we present a solution that establishes secure connections between any two WiFi devices, without having users enter passwords or use pre-shared secret keys.
Download or read book Enhancing Wireless Security Through Cross layer Approaches written by Shaxun Chen and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to wired networks, wireless networks are more susceptible to security attacks due to the shared medium and the broadcast nature. These attacks include but are not limited to sniffer attack, identity spoofing attack, and denial-of-service (DoS) attack. In this dissertation, instead of viewing wireless as a vulnerability, we try to explore novel dimensions of wireless network characteristics to enhance wireless security. The information extracted from new dimensions is utilized in conjunction with the knowledge from other network layers. Through such cross-layer approaches, we defend against attacks and build more secure wireless networks and mobile systems. We first look at the signal characteristics of wireless channels. The reciprocity property claims that bidirectional wireless channel states should be identical between two transceivers at a given instant of time. We utilize this channel state as an inherent shared secret between two parties, and propose a new and more secure method defending against narrow-band jamming attacks by combining physical layer and MAC layer information. We also investigate unremarkable but potentially useful information in specific types of wireless networks. In cognitive radio networks, TV towers and wireless microphones are two main types of primary users. The primary user emulation (PUE) attack which targets at the latter type is extremely difficult to detect due to their low transmission power and mobility. We innovatively analyze the correlation between the sound and RF signal emitted by wireless microphones to defend against mobile PUE attacks. In wireless surveillance camera networks, spoofing attacks are easier to launch than their wired counterparts. We combine the camera sensor pattern noise as well as wireless channel signatures to detect wireless camera spoofing attacks, where physical layer and application layer information are exploited simultaneously. Smartphones have dominated the growth of wireless market in the recent years. User authentication of smartphones and mobile apps is typically achieved by passwords or gesture locks. Although most of today's smartphones are equipped with a front-facing camera, face authentication is rarely used in practice because 2D face recognition can be easily cheated by photos or pre-recorded videos. We inventively make use of the readings from built-in motion sensors of smartphones. Combining with camera data, we build a fast yet secure face authentication system for mobile devices and apps. The security and efficiency of mobile device authentication can be largely improved by adopting our cross-layer approach.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses and summarizes current research issues, identifies challenges, and outlines future directions for proactive and dynamic network defense. This book also presents the latest fundamental research results toward understanding proactive and dynamic network defense by top researchers in related areas. It includes research results that offer formal frameworks to define proactive and dynamic network defense, and develop novel models to analyze and evaluate proactive designs and strategies in computer systems, network systems, cyber-physical systems and wireless networks. A wide variety of scientific techniques have been highlighted to study these problems in the fundamental domain. As the convergence of our physical and digital worlds grows fast pace, protecting information systems from being tampered or unauthorized access is becoming one of the most importance issues. The traditional mechanisms of network defense are built upon a static, passive, and reactive nature, which has insufficient to defend against today's attackers that attempt to persistently analyze, probe, circumvent or fool such mechanisms. It has not yet been fully investigated to address the early stage of “cyber kill chain” when adversaries carry out sophisticated reconnaissance to plan attacks against a defense system. Recently, proactive and dynamic network defense has been proposed as an important alternative towards comprehensive network defense. Two representative types of such defense are moving target defense (MTD) and deception-based techniques. These emerging approaches show great promise to proactively disrupt the cyber-attack kill chain and are increasingly gaining interest within both academia and industry. However, these approaches are still in their preliminary design stage. Despite the promising potential, there are research issues yet to be solved regarding the effectiveness, efficiency, costs and usability of such approaches. In addition, it is also necessary to identify future research directions and challenges, which is an essential step towards fully embracing proactive and dynamic network defense. This book will serve as a great introduction for advanced-level computer science and engineering students who would like to start R&D efforts in the field of proactive and dynamic network defense. Researchers and professionals who work in this related field will also find this book useful as a reference.

Download or read book Interference in Large Wireless Networks written by Martin Haenggi and published by Now Publishers Inc. This book was released on 2009 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since interference is the main performance-limiting factor in most wireless networks, it is crucial to characterize the interference statistics. The main two determinants of the interference are the network geometry (spatial distribution of concurrently transmitting nodes) and the path loss law (signal attenuation with distance). For certain classes of node distributions, most notably Poisson point processes, and attenuation laws, closed-form results are available, for both the interference itself as well as the signal-to-interference ratios, which determine the network performance. This monograph presents an overview of these results and gives an introduction to the analytical techniques used in their derivation. The node distribution models range from lattices to homogeneous and clustered Poisson models to general motion-invariant ones. The analysis of the more general models requires the use of Palm theory, in particular conditional probability generating functionals, which are briefly introduced in the appendix.
Download or read book Guide to Wireless Network Security written by John R. Vacca and published by Springer. This book was released on 2016-04-01 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. INTRODUCTION With the increasing deployment of wireless networks (802. 11 architecture) in enterprise environments, IT enterprises are working to implement security mechanisms that are equivalent to those existing today for wire-based networks. An important aspect of this is the need to provide secure access to the network for valid users. Existing wired network jacks are located inside buildings already secured from unauthorized access through the use of keys, badge access, and so forth. A user must gain physical access to the building in order to plug a client computer into a network jack. In contrast, a wireless access point (AP) may be accessed from off the premises if the signal is detectable (for instance, from a parking lot adjacent to the building). Thus, wireless networks require secure access to the AP and the ability to isolate the AP from the internal private network prior to user authentication into the network domain. Furthermore, as enterprises strive to provide better availability of mission-critical wireless data, they also face the challenge of maintaining that data's security and integrity. While each connection with a client, a supplier or a enterprise partner can improve responsiveness and efficiency, it also increases the vulnerability of enterprise wireless data to attack. In such an environment, wireless network security is becoming more important every day. Also, with the growing reliance on e-commerce, wireless network-based services and the Internet, enterprises are faced with an ever-increasing responsibility to protect their systems from attack.
