Park and Kumar Granted a US Patent for a Computationally Efficient Method for Providing Privacy-Preserving Authentication
Drs. Jerry Park and Vireshwar Kumar (Virginia Tech alumnus and Park’s former PhD advisee) are the co-inventors of a US patent, entitled “Group signatures with probabilistic revocation (US Patent No. 10,326,602),” that was recently published by the US Patent & Trademark Office. Digital group signatures is an elegant, but computationally expensive, method for providing privacy-preserving authentication in a number of emerging applications, including vehicle-to-everything (V2X) safety applications, electronic voting, electronic auctions, etc. The primary drawback of group signature schemes, which is limiting their application to commercial products, is the high computational complexity of their revocation procedure. The revocation procedure, which is a critical part of group signatures, is needed to revoke outdated or invalid keys. In this patent, the inventors describe a novel revocation procedure whose computational complexity is much lower compared to that of the prior art. Significant computational efficiency is achieved by employing a novel, probabilistic algorithm for evaluating the revocation status of each group signature.

Wireless @ Virginia Tech Student Sudeep Bhattarai Contributes in the Design and Deployment of the First Prototype ESC
Sudeep Bhattarai, a PhD student advised by Professor Jerry Park in the Department of Electrical and Computer Engineering, actively contributed in the design, development and deployment of the first prototype Environmental Sensing Capability (ESC) in San Francisco during his summer research at Google. This deployment is the first step towards enabling shared usage of 150 MHz of the radio spectrum in the 3.5 GHz band, also known as the Citizens Broadband Radio Service (CBRS) band.
The U.S. Federal Communications Commission (FCC) has recently opened the 3.5 GHz band for sharing between the Navy’s shipborne radars (incumbent users) and broadband communication systems (CBRS devices). A fundamental requirement for shared use of this band is that a dedicated network of sensors called ESCs must detect incumbent operations and alert the spectrum manager. The spectrum manager for the CBRS band is called the Spectrum Access System (SAS). SAS maintains orderly use of the band while protecting incumbents and coordinating spectrum use among CBRS devices. Upon receiving an alert from the ESC, the SAS reconfigures CBRS devices under its control to avoid harmful interference to the Navy radar.
Google, among others, has applied to the FCC to operate both a SAS and an ESC, and has been actively developing software and hardware capabilities to detect incumbent radars. The goal is to deploy a network of ESCs along the U.S. coastline and allow CBRS devices to operate in the coastal areas provided that they do not cause harmful interference to the incumbent users.

Papers from Dr. Jerry Park’s Group Featured in IEEE Communications Society (ComSoc) Best Readings in Cognitive Radio (CR)
The IEEE Communications Society (ComSoc) has selected two papers from Dr. Jerry Park’s ARIAS (Advanced Research in Information Assurance and Security) research group for inclusion in the ComSoc’s Best Readings in Cognitive Radio (CR) list. The first paper entitled “Defense against primary user emulation attacks in cognitive radio,” written by R. Chen, J. Park and J. H. Reed was originally published in January 2008 in the IEEE Journal on Selected Areas in Communications. This paper systematically shows that “primary user emulation” attacks can result in severe interference and significantly reduce spectrum utilization. To address the problem, the authors propose a transmitter verification scheme that is able to identify whether a signal is being transmitted from primary users or not by using an estimate of the transmitter’s location and the characteristics of the signal itself.
The second paper entitled “Toward secure distributed spectrum sensing in cognitive radio networks,” was coauthored by R. Chen, J. Park, Y. T. Hou, and J. H. Reed, and was originally published in April, 2008 in the IEEE Communications Magazine. This paper introduced pioneering work on mitigating security threats such as incumbent emulation and spectrum sensing data falsification threats in cognitive radio networks. The paper also described countermeasures for addressing those threats. The IEEE ComSoc’s Best Readings in Cognitive Radio (CR) list is a recommended reading list of books, articles and papers on Cognitive Radio Communications and Networking that are of interest to the IEEE ComSoc readership. IEEE ComSoc’s Best Readings in Cognitive Radio (CR) list is available here.
Jerry Park Awarded Major NSF Grant To Address Dynamic Exclusion Zones in Radio Spectrum
The Federal Communications Commission is opening up bands of spectrum that were previously restricted to a few priority users, including the military. Virginia Tech College of Engineering professor Jung-Min “Jerry” Park is leading a $730,000 National Science Foundation grant collaboration with William Lehr from the Massachusetts Institute of Technology, to find ways to make this transition as smooth as possible. The FCC’s plans to provide incumbent users with a wide, insulating boundary, often called an exclusion zone, separating them from new users. In this type of environment, incumbent users have first dibs on the spectrum, and the secondary users can access what’s left over.
Park, of the Bradley Department of Electrical and Computer Engineering, and his collaborators intend to develop a new strategy supporting blueprints for flexible exclusion zones, or an adjustable boundary, that can respond dynamically to the incumbent protection requirements and the interference environment. In this way, incumbent users will still have safe, clear access to their frequencies, but secondary users will be able to make efficient use of the spectrum when it’s free. Read more
