Stir-Ing The Wireless Medium With Self-Tuned, Inference-Based, Real-Time Jamming, Bruce Debruhl, Yu Seung Kim, Zachary Weinberg, Patrick Tague Sep 2012

Stir-Ing The Wireless Medium With Self-Tuned, Inference-Based, Real-Time Jamming, Bruce Debruhl, Yu Seung Kim, Zachary Weinberg, Patrick Tague

Jamming, broadcasting to intentionally interfere with wireless reception, has long been a problem for wireless systems. Recent research demonstrates numerous advances in jamming techniques that increase attack efficiency or reduce the probability an attack will be detected by choosing attack parameters based on a system’s configuration. In this work, we extend the attacker’s capabilities by modifying the attack parameters in response to the observed performance of the target system, effectively creating a feedback loop in our attack model. This framework allows for more intricate attack models that are tuned online allowing for closer to optimal attacks against legitimate systems. To …


All Your Jammers Belong To Us - Localization Of Wireless Sensors Under Jamming Attack, Yu Seung Kim, Frank Mokaya, Eric Chen, Patrick Tague May 2012

All Your Jammers Belong To Us - Localization Of Wireless Sensors Under Jamming Attack, Yu Seung Kim, Frank Mokaya, Eric Chen, Patrick Tague

Accurately determining locations of nodes in mobile wireless network is crucial for a myriad of applications. Unfortunately, most localization techniques are vulnerable to jamming attacks where the adversary attempts to disrupt communication between legitimate nodes in the network. In this paper, we propose an approach to localize a wireless node by using jamming attack as the advantage of the network. Our localization technique is divided into two steps. First, we discover the location of the jammer using power adaptation techniques. Then, we use these properties to extrapolate the locations of jammed nodes. We design a localization protocol using this technique, …


S-Span: Secure Smart Posters In Android Using Nfc (Demo), Jason Wu, Lin Qi, Nishant Kumar, Ram Shankar Siva Kumar, Patrick Tague May 2012

S-Span: Secure Smart Posters In Android Using Nfc (Demo), Jason Wu, Lin Qi, Nishant Kumar, Ram Shankar Siva Kumar, Patrick Tague

Smart posters are a promising new use case for NFC-enabled mobile devices, but to date there has been a general lack of security mechanisms for NFC smart posters. We present S-SPAN - a secure smart poster system consisting of three parts: an administrative web interface for managing posters, a backend server for storing and serving data, as well as an Android application for end-users. S-SPAN enforces confidentiality and integrity of smart poster data as well as authentication/authorization of administrators and end-users, thus ensuring that only authorized users can access the content.


Living With Boisterous Neighbors: Studying The Interaction Of Adaptive Jamming And Anti-Jamming, Bruce Debruhl, Patrick Tague May 2012

Living With Boisterous Neighbors: Studying The Interaction Of Adaptive Jamming And Anti-Jamming, Bruce Debruhl, Patrick Tague

Jamming has long been a problem in wireless communications, but with recent advances in adaptive jamming, adaptive anti-jamming, and other advanced physical layer security techniques, it is hard to understand whether we can keep the jammer at bay. In this work, we consider this problem and introduce a game-theoretic framework which gives us a tool to analyze the complex adaptive jamming and anti-jamming space. To illustrate the strengths and weaknesses in intelligent jamming and anti-jamming techniques, we present a straightforward two-player instance and analyze a number of possible jamming and anti-jamming techniques.


Jamming-Resistant Distributed Path Selection On Wireless Mesh Networks (Demo), Yu Seung Kim, Patrick Tague Feb 2012

Jamming-Resistant Distributed Path Selection On Wireless Mesh Networks (Demo), Yu Seung Kim, Patrick Tague

Patrick Tague

Wireless mesh network is an emerging network architecture which have been actively standardized for the last few years. Because of its flexible network architecture, wireless mesh network can provide alternative paths even when some of wireless links are broken by node failures or intended attacks. Among various types of mesh network, we focus on the most recent mesh standard, IEEE 802.11s and its resiliency to jamming attack. In the demo, we show jamming effects on wireless mesh network and the performance of the hybrid wireless mesh protocol (HWMP) defined in IEEE 802.11s and our proposed distributed path selection protocol.

A Toolbox To Explore The Interaction Of Adaptive Jamming And Anti-Jamming (Demo), Bruce Debruhl, Yu Seung Kim, Patrick Tague

Jamming has long been a problem in wireless communications. Recently, adaptive jamming and anti-jamming techniques have been proposed which aim to use feedback to better perform their task. For an anti-jamming receiver this means detecting jamming and adapting its protocol appropriately. For a jammer this means using feedback from the legitimate system to design a high-impact, low-power, hard-to-detect attack. In this work we introduce a toolbox to allow users to tests the performance of adaptive jamming and anti-jamming on the USRP2 radio platform. These test provide an important function by letting developers understand how well new protocols work against evolving …


Mitigation Of Periodic Jamming In A Spread Spectrum System By Adaptive Filter Selection, Bruce Debruhl, Patrick Tague Jan 2012

Mitigation Of Periodic Jamming In A Spread Spectrum System By Adaptive Filter Selection, Bruce Debruhl, Patrick Tague

Patrick Tague

Jamming has long been a problem in wireless communication systems. Traditionally, defense techniques have looked to raise the cost of mounting an equally effective jamming attack. One technique to raise the cost of jamming is direct sequence spread spectrum (DSSS) which spreads data over a wider bandwidth and has built-in error correction. To work around this, attackers have developed intelligent jamming techniques to minimize the cost of mounting attacks on these systems. To lower the cost of attacking a DSSS system, an attacker can use periodic jamming which alternates between an attacking and sleeping state. Previously, a digital filter has …


Shortmac: Efficient Data-Plane Fault Localization, Xin Zhang, Zongwei Zhou, Hsu-Chun Hsiao, Tiffany Kim, Adrian Perrig, Patrick Tague Jan 2012

Shortmac: Efficient Data-Plane Fault Localization, Xin Zhang, Zongwei Zhou, Hsu-Chun Hsiao, Tiffany Kim, Adrian Perrig, Patrick Tague

Patrick Tague

The rising demand for high-quality online services requires reliable packet delivery at the network layer. Dataplane fault localization is recognized as a promising means to this end, since it enables a source node to localize faulty links, find a fault-free path, and enforce contractual obligations among network nodes. Existing fault localization protocols cannot achieve a practical tradeoff between security and efficiency and they require unacceptably long detection delays, and require monitored flows to be impractically long-lived. In this paper, we propose an efficient fault localization protocol called ShortMAC, which leverages probabilistic packet authentication and achieves 100 – 10000 times lower …


Survivable Smart Grid Communication: Smart-Meters Meshes To The Rescue, Arjun Athreya, Patrick Tague Dec 2011

Survivable Smart Grid Communication: Smart-Meters Meshes To The Rescue, Arjun Athreya, Patrick Tague

Patrick Tague

Smart grids are critical cyber-physical infrastructures in the world now. Since these infrastructures are prone to large scale outages due to disasters or faults, a resilient and survivable communication architecture is desired. In this work, we propose a resilient and survivable hierarchical communication architecture for the smart grid that mirrors the hierarchy of the existing power grid. Post-disaster resilience in grid communication is achieved through the grid flattening process. This process involves smart-meters and other disaster surviving elements of higher system levels of the grid forming a wireless mesh network. The flattened network of grid elements with one-hop communication links …
