Hi, I'm Raymond
Huahong Tu
My mission is to make an impact to our society through cybersecurity research and education.
News
I accepted a position as an Assistant Clinical Professor at the University of Maryland, College Park starting in Jan 2018. I will serve as a research educator and lead the Capital One Machine Learning FIRE innovation and research stream focused on the Computer Science practices of machine learning, data analytics, and cybersecurity.
This is what I do
Research and Development
My current research focuses on using cybersecurity techniques to solve the telephone spam, scam, and phishing problem. Telephone spam, including scam, phishing, robocall, and telemarketing, has become an increasingly prevalent issue worldwide. Today, solutions primarily rely on blacklists of known scam numbers do not work effectively on spam calls when the caller ID has been spoofed. My recent development proposed a novel approach to address the weaknesses of the caller ID transmission scheme such that the caller ID would be verified before transmission. This allows effective and immediate blocking of spoofed phone numbers and helps to ensure the communication is trusted. We developed a proof-of-concept prototype based on out-of-band transmission and we seek industry partnerships to make this work on all Public Switched Telephone Network devices.
Research and Teaching Interests
Cybersecurity, network security, web security, information security, social engineering, communication protocols, authentication schemes, identity management, cybercrime analytics, adversarial machine learning, systems engineering.
Software and Hacks
I also like to work on various software and coding projects. I like to build on web, mobile, and service frameworks.
