Welcome!
I’m a Ph.D. student at Xidian University. My research focuses on searchable encryption and secure multi-party computation. I develop privacy-enhancing techniques to solve data security and integrity problems for databases and cloud storage.
🔥 News
- 2024.8: New Paper on “Scalable Equi-Join Queries over Encrypted Database” Accepted by ACM CCS 2024
- 2025.？: I will be a visiting student for one year at RMIT University in Melbourne, Australia, working with Professor Xun Yi’s research group. (I haven’t left yet, as I’m still waiting for my visa…)
