Secure communication technology research at VCU College of Engineering receives Commonwealth Cyber Initiative support
The Commonwealth Cyber Initiative’s (CCI) Northern Virginia Node recently awarded a $75,000 grant to Supriyo Bandyopadhyay, Ph.D., professor in the Department of Electrical and Computer Engineering at the Virginia Commonwealth University (VCU) College of Engineering, to develop an ultra-subwavelength microwave polarization switch for secure communication. The one-year grant comes through the Cyber Acceleration, Translation and Advanced Prototyping for University Linked Technology (CATAPULT) Fund. It supports Bandyopadhyay’s project, “An ultra-subwavelength microwave polarization switch for secure communication,” which develops a nanomagnet-based antenna integrated with a piezoelectric component. This system can switch the polarization of electromagnetic beams at specific microwave frequencies to enable secret communication between two points without traditional encryption methods. “Secret communication sheds the need for encryption,” Bandyopadhyay said. “Any cryptography can be broken, but this scheme does not use cryptography for secret communication and does not suffer from this vulnerability. It is also entirely based on hardware and cannot be hacked.” The technology offers significant benefits for banking, healthcare and government communications where data security is critical because a hardware-based approach makes it immune to software hacking. Another result of the research is antenna miniaturization, with antenna sizes several orders of magnitude smaller than the radiated wavelength. This addresses limitations in algorithms, physical size and power requirements that current secure communication systems face. Bandyopadhyay is collaborating with two researchers from the Department of Electrical and Computer Engineering at Virginia Tech and Erdem Topsakal, Ph.D., senior associate dean for strategic initiatives and professor in the Department of Electrical and Computer Engineering at VCU. Students involved in the project will be trained in antenna engineering, microwaves and communication engineering, gaining skills increasingly vital in today’s connected world.
