Welcome to the ARIAS website!

The Advanced Research in Information Assurance and Security (ARIAS) lab is a research group within the Department of Electrical and Computer Engineering at Virginia Tech.

Established in 2003 by Dr. Jung-Min "Jerry" Park, ARIAS specializes in security issues related to wireless networks and cyber security with an emphasis on cognitive radios.

One of the critical challenges that needs to be addressed is the security and privacy issues. This problem is paramount when federal government systems, including DoD systems coexist with non-government systems in the same spectrum bands.

Welcome to the Laboratory for Advanced Research in Information Assurance and Security - ARIAS

Mission Statement

The mission of the ARIAS laboratory is to study and solve challenging problems in wireless networks and cyber security, with a particular focus on cognitive radio networks, related technologies for spectrum sharing, and their security implications. The current research thrusts of ARIAS include the following areas:

  • Security and privacy in wireless systems and networks
  • Spectrum enforcement, security, and privacy in shared spectrum access
  • Security issues in cognitive radio networks
  • Security issues in LTE/LTE-A and 5G cellular networks
  • Co-design and co-existence of heterogeneous wireless systems, including coexistence of radar and communication systems
  • Supporting mobility in opportunistic spectrum access
  • Security and privacy in wireless healthcare
  • Prototyping and testing using large-scale cognitive radio testbeds

  • News alert! Dr. Jerry Park among the Class of 2017 IEEE Fellows. Read more!

    Dr. Jerry Park, the founding director of ARIAS, is the site director of an NSF-sponsored multi-university Industry-University Cooperative Research Center (I/UCRC) called Broadband Wireless Access & Applications Center (BWAC).

    About BWAC:

    BWAC logoThe Broadband Wireless Access & Applications Center (BWAC) is a multi-university research center sponsored by the National Science Foundation (NSF) under its Industry-University Cooperative Research Center (I/UCRC) program. BWAC partner universities (sites) include University of Arizona, Auburn University, University of Virginia, Virginia Tech, the University of Notre Dame and the University of Mississippi. The primary mission of BWAC is to work with industry and academic partners to pursue large-scale research projects, address challenging spectrum access problems through novel broadband technologies, and create new visions for the wireless industry. BWAC researchers work closely with industrial partners, through its Industrial Affiliates Program, to develop novel and innovative wireless technologies and applications. Please visit the BWAC website here for current and up-to-date information on our research projects and activities.

    SPECIAL NOTE: The spring BWAC board meeting is May 17 - 18, 2017, hosted by Virginia Tech at the Virginia Tech Research Center in Arlington, VA. Please visit the BWAC website at for more information. Additional details will be posted as they become available.

    Dr. Jerry Park Receives $375K NSF Grant

    Jerry Park (VT PI), in collaboration with Temple University and the University of Arizona, won $1.1M for a project titled “Coexistence of Heterogeneous Wireless Access Technologies in the 5 GHz Band.” VT’s portion in this project is $375K. This project aims to create solutions caused by interference of unlicensed‐LTE, Wi-Fi, and Dedicated Short‐Range Communications (DSRC) operating in the same band and generalize these solutions to new technologies beyond today’s LTE, Wi-Fi, and DSRC systems.
