The role of spectrum as an important economic growth engine was brought forth in the recently announced National Broadband Plan as well as in the President’s Council of Advisors on Science and Technology (PCAST) report entitled “Realizing the Full Potential of Government-Held Spectrum to Spur Economic Growth”. A broad range of innovative spectrum access technologies will need to be developed to realize the recommendations of the PCAST report, which includes the ambitious goal of sharing underutilized Federal spectrum and identifying 1,000 MHz of Federal spectrum as part of an effort to create “the first shared-use spectrum superhighways”. In the shared spectrum access model, a heterogeneous mix of wireless systems of differing access priorities, QoS requirements, and transmission characteristics need to coexist without causing harmful interference to each other. One of the critical challenges that need to be addressed to realize the shared access model is the development of technologies for spectrum enforcement and security. One of the primary concerns in spectrum sharing is the harmful interference caused by malfunctioning devices or malicious users that violate spectrum access rules. Another concern is the threat to the primary users’ operational privacy. Recent findings suggest that through seemingly innocuous queries to the geolocation database, adversarial secondary users can infer the operational characteristics of the primary users. In this presentation, I will describe the key problems in spectrum enforcement and security, and also discuss possible approaches for addressing those problems.

Jung-Min “Jerry” Park received a Ph.D. degree in electrical and computer engineering from Purdue University in 2003. He is currently an associate professor in the Department of Electrical and Computer Engineering at Virginia Tech, and the site director of an NSF-sponsored Industry-University Cooperative Research Center (I/UCRC) called Broadband Wireless Access & Applications Center (BWAC). As the site director of the Center, Park is leading several sponsored research projects on wireless networks and cyber security. He is widely recognized for his pioneering work on security and enforcement problems in cognitive radio networks and spectrum sharing. His research interests include cognitive radio networks, spectrum sharing technologies, network security and privacy, and applied cryptography. Park’s current or recent research sponsors include the NSF, National Institutes of Health (NIH), Defense Advanced Research Projects Agency (DARPA), Office of Naval Research (ONR), SANS (SysAdmin, Audit, Network Security) Institute, Motorola Solutions, Samsung Electronics, SCA Techniques, and other industry sponsors. He is a recipient of a 2008 NSF Faculty Early Career Development (CAREER) Award, a 2008 Hoeber Excellence in Research Award, and a 1998 AT&T Leadership Award.
