Mitigation Methods to Protect the LTE Systems against LTE Control Channel Spoofing.

Critical modifications to the 3GPP LTE (Long Term Evolution)/ 3GPP LTE advanced specifications are proposed to mitigate the effect of LTE control channel spoofing. The effect of LTE control channel spoofing has been analyzed and tested. The test results show that an attacker can prevent new UEs from camping on any certain LTE cell. Thus we have proposed certain modifications that are necessary to invulnerable the LTE systems against these types of attacks. Read more:

Our Students in Action!

Sollenberger

Eric Sollenberger presented a short paper at the IEEE VTC-Fall in Boston on September 7: “Test & Evaluation of Cognitive and Dynamic Spectrum Access Radios using The Cognitive Radio Test System,” IEEE VTC-Fall, Boston, MA, September 6-9, 2015.

 

 

 

Dhiraj

SaiDhiraj Amuru recently published a journal paper titled “Optimal jamming against digital modulation". This paper shows that a) the jammer must not always match its signal to the victim's signaling scheme and b) AWGN is not always the optimal jamming signaling scheme against digital amplitude-phase modulated constellations.

Jakubisin Daniel Jakubisin and Dr. Buehrer have developed a new algorithm to address detection of signals in the presence of co-channel interference. The algorithm relies on a factor graph model of the received signal and employs a new approximation to the sum-product algorithm in order to approach joint MAP detection of the desired and interfering signals. As a result of the work, reliable signal detection is enabled in challenging cases such as single antenna reception, multipath channels, and similar signal and interference power levels---cases where other algorithms often fail. The work is to be presented at the upcoming IEEE MILCOM conference and has also been made available here.

BWAC In the News:

 

Dr. Jerry Park

Dr. Jerry Park Promoted to Professor
Dr. Jung-Min "Jerry" Park was promoted to Professor by the Virginia Tech Board of Visitors on June 3. Dr. Park is the Associate Director of Affiliate Relations for Wireless @ Virginia Tech, Site Director for the Virginia Tech BWAC site, and is the founding director of the ARIAS Lab dedicated to security issues in wireless networking and cyber security.

 

 

 

Dr. Jerry Park Jerry Park is the PI of an NSF grant titled "Collaborative research: Dynamic exclusion zones: Balancing incumbent protection and spectrum utilization efficiency" with a total budget of $731K. This is a collaborative research project between Park (lead investigator) and W. Lehr (at MIT). The primary goal of the project is to develop a framework for implementing Incumbent Protection Zones that take advantage of the network of SAS (Spectrum Access System) databases and spectrum sensing data to adjust the geo-contours of exclusion zones dynamically. This will expand opportunities for Secondary Users to co-exist with Incumbent Users without causing harmful interference. This research is intended to provide a practical framework that is both technically and economically viable for implementing incentive-compatible dynamic sharing solutions as part of the SAS framework.

 

 

Dr. Jerry Park

Jerry Park is a co-PI of a major NSF grant titled "Advanced materials manufacturing, sensing, and wireless controls for intelligent automobile environments" with a total budget of $1.15M. This project will involve research collaboration between Prof. Park, Prof. S. Taheri (VT's Dept. of Mechanical Engineering), Prof. M.R. Hajj (VT's Dept of Biomedical Engr. and Mechanics), Prof. S. Priya (VT's Dept. of Mechanical Engineering), and Prof. S. Trolier-McKinstry (Penn State Univ.). ​In intelligent vehicles envisioned to be manufactured in the near future, safety-critical components, such as tires and seat belts, play critical roles in the development of intelligent controls as​ they can provide information on the most relevant parameters such as friction, slip, pressure, and driver​ condition​s​. ​ The​ overall goal​ of the project is to actively monitor th​o​se parameters through embedded sensors based​ upon piezoelectrics and dielectrics.​ Park's group will take the lead in the design and implementation of the​ mechanisms and p​rotocols needed to enable reliable, secure, and efficient​ wireless​ transmission of the sensor-collected data.

 

 
 

 

Dr. Park and Dr. Reed Jeff Reed (PI) and Jerry Park (co-PI) have been awarded a grant by NSF to organize a major workshop on Enhancing Access to the Radio Spectrum (EARS). This EARS Workshop will be held on October 19-20, 2015 in Arlington, VA. At this workshop, an interdisciplinary group of highly-visible academic researchers, relevant government officials, and industry stakeholders will gather to discuss technologies and polices that will enable us to unlock the true potential of the spectrum while respecting the needs of incumbent users. This group will create a vision for future spectrum use,identifying the problems to be overcome, the research needed to overcome these problems, and the financial and human capital resources necessary to support this vision.
