I am now a Ph.D. candidate in Computer Science Dept. at Stony Brook University. I am doing research in Network Security and Applied Cryptography Lab, headed by my advisor Prof. Radu Sion. Before I came to Stony Brook, I obtained my B.S. from Zhejiang University.

Research Interests

My research interests are primarily in the areas of Network Security, Privacy and Applied Cryptography.

Reading List

You can find my reading list here: Yao's Reading List

Research Projects

• Privacy in micropayments.
  We designed a lightweight micropayment scheme for network services, providing anonymity, privacy and overspending prevention. (paper under submission)
• Price of privacy.
  This project explores the underlying cost of CPU cycles and network transfers. It then extends to the analysis of the cost of various cryptographic operations, protcols.
• Secure Worm
  Strong regulatory compliant storage system with Tamper-proof hardware. Developed a expiration optimization data structure. Built the cost model for the system.

Course Projects

• WEP Cracking Project Dec 2007
  Implemented an application that breaks into a 128 bit WEP protected wireless network with ethernet-level access to a network interface in Linux.

• Developed a Market Timing Model using Dynamic Programming and Hidden Markov Model
  The model makes decision of selling or buying stocks by predicting the potential price movements. (Computational Finance Project; See my project: http://2007cse691.googlepages.com/)

• Implement a supervised leaning framework for object detection in images using Kernel PCA and Adaboost (Computer Vision Project)
