Dr. Jerry Park Receives CISCO Grant

MosaffariJerry Park recently received a Cisco Faculty Research Award.  The title of the project is “Anonymity-Preserving Authentication for Large Networks”.   Cisco Research Awards are one-year awards structured as unrestricted gifts to universities to support the work of faculty members that are working on innovative solution approaches to challenging problems in networking,  programmable networks, and cybersecurity.

In many network applications, we need to be able to authenticate the data while, at the same time, protect the anonymity or privacy of the data source—in other words, anonymity-preserving authentication (APA) is needed.  Existing approaches for APA have limited utility in large networks due to their high computational complexity and/or high communication overhead.  Park and his team will investigate novel approaches for APA and study the performance and security requirements of a number of important applications which require APA.

Wireless @ Virginia Tech awarded grants to help ease shift to sharing of radio bands

The coming technical shift to a shared use of some of the nation's radio bands -- used for activities including television and radio broadcasts, cell phones, military communications, and air-traffic control -- means economic opportunity and more connected devices. However, users who previously had sole use of frequencies in these bands must find a way to protect their assets and privacy. These users, including the military, find themselves at some level in a position analogous to beachfront property owners when a previously private beach goes public. Military groups that currently have sole access to some of the radio bands to be shared are facing new issues that include: privacy, rogue users, jammers, hackers, and legacy equipment. The U.S. military, already confronted with many of these problems when it operates abroad, will now face similar challenges at home. Sharing radio bands, or frequencies, requires engineers who can design systems that can adapt, plus devices that can collaborate on when, and on what frequency, each will transmit. Read more..

Guest Lecture Friday, August 21:

"Secure and Private Data Aggregation for Energy Consumption Scheduling in Smart Grids"

Prof. Mohammad Hossein Manshaei, Isfahan University of Technology. Friday, August 21st, 10:00 a.m. - 11:00 a.m., Durham 261

Abstract: The recent proposed solutions for demand side energy management leverage the two-way communication infrastructure provided by modern smart-meters and sharing the usage information with the other users. In this talk, we first highlight the privacy and security issues involved in the distributed demand management protocols. We propose a novel protocol to share required information among users providing privacy, confidentiality, and integrity. We also propose a new clustering-based, distributed multi-party computation (MPC) protocol. Through simulation experiments we demonstrate the efficiency of our proposed solution. The existing solutions usually thwart selfish and malicious behavior of consumers by deploying billing mechanisms based on total consumption during a few time slots. However, the billing is typically based on the total usage in each time slot in smart grids. In the second part of this talk, we formally prove that under the per-slot based charging policy, users have incentive to deviate from the proposed protocols. We also propose a protocol to identify untruthful users in these networks. Finally, considering a repeated interaction among honest and dishonest users, we derive the conditions under which the smart grid can enforce cooperation among users and prevents dishonest declaration of consumption. The presentation also includes a brief introduction to other research activities in my research group, such as computational biology, selfish behavior analysis of mobile users in 5G, and security games.

Bio: Mohammad Hossein Manshaei received the BSc degree in electrical engineering and the MSc degree in communication engineering from the Isfahan University of Technology in 1997 and 2000, respectively. He received another MSc degree in computer science and the PhD degree in computer science and distributed systems from the University of Nice Sophia-Antipolis, France, in 2002 and 2005. He did his thesis work at INRIA, Sophia-Antipolis, France. He is currently an assistant professor at the Isfahan University of Technology, Iran. From 2006 to 2011, he was a senior researcher and lecturer at EPFL, Switzerland. He held visiting positions at the UNCC and at the NYU. His research interests include wireless networking, wireless security and privacy, smart grid, and game theory.

Dr. Jeff Reed to Demo New Dynamic Spectrum Access System for Next Generation Public Safety Radios

Wireless @ Virginia Tech continues to lead the way in solving pressing issues within the wireless communications market by successfully implementing a dynamic spectrum access (DSA) system for next generation Public Safety radios.  The DSA system, a custom-designed frequency translator/repeater for FD-LTE, allows using commercially available technology and public safety LTE user equipment (UE) operating in any band to operate in the new 3.5 GHz band on a secondary basis.  The primary users on this band, comprised between 3550 and 3700 MHz, are high-power and low duty cycle radar systems, and fixed satellite receive stations.

The frequency translator/repeater allows fast switching of the carrier frequency.  Controlled by a Spectrum Access System (SAS), the eNode-B and attached UEs operate as usual and collect LTE radio performance parameters that the SAS can exploit.  “Being able to expand the coverage and available bandwidth is important to the future of public safety.” said Dr. Jeffrey Reed.  “The system that we have developed will work with the developing spectrum sharing paradigm and shows a pathway to a solution for public safety.”

The team of researchers will demonstrate one of the first broadband public safety DSA radio systems using a Rhode & Schwartz CMW500 eNodeB emulator and a Motorola Solutions LEX L10 and LEX 700 public safety UE at the 25th Anniversary Wireless Symposium & Summer School, May 27 - 29, 2015 at Virginia Tech. This demonstration will show the additions that are needed to existing wireless devices to make them DSA-capable.

Jeff Reed, Ph.D., the Willis G. Worcester Professor in the Bradley Department of Electrical and Computer Engineering, led the development of the dynamic spectrum access system with sponsorship by the Center for Innovative Technology and the office of the Vice President of Information Technology at Virginia Tech.

Indoor Propagation Modeling and Channel Characterization for the 3.5 GHz band.

Sean HaM.S. student Sean Ha (advisor: Dr. Jeffrey H. Reed) has carried out an indoor propagation measurement campaign to model the 3.5 GHz band through documentation and analysis of captured channel characterization parameters such as large scale path loss, log-normal shadowing, and multipath delay spread characteristics. Measurements were carried out in traditional indoor office, hallway, lobby, classroom, computer laboratory, and hospital environments.

Results were compared to indoor path loss models used for wireless local area network (WLAN) planning in the low GHz range to investigate the applicability of extending these models to 3.5 GHz. The campaign was carried out using Virginia Tech's VIPER channel measurement system - a software-defined vector channel sounder, which allowed for an additional feasibility study of employing multi-antenna systems to increase performance in indoor environments. The 3.5 GHz band is expected to play a significant role in shaping the future of spectrum sharing, as the FCC has recently proposed a shared three-tier authorization mechanism for the band to promote unlicensed and opportunistic spectrum access. However, since the adoption of this band is new, there is a distinct shortage of propagation data and accurate channel modeling, both of which are instrumental in evaluating the performance and feasibility of wireless systems. Consequently, there is high demand for 3.5 GHz propagation research, focusing on channel characterization and spectral co-existence with primary band users.

This work is sponsored by the Office of the Secretary of Defense (OSD).
