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


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. It was established in 2003, and its mission 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


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). 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.
