I obtained my PhD degree this summer, and now I am an associate researcher in OceanBase, Ant Group.

I am actively finding interesting problems in research and trying to learn some lessons from them! So, please contact me if any collaboration is possible!

Thanks to my supervisor Jian Liu and prior collaborators in the past five years. They help me understand some techniques in encrypted databases including order-preserving encryption, oblivious algorithms, functional encryption, and homomorphic encryption.

In all listed publications below, I am the first author/corresponding author/co-first author.

📝 Publications (Conference)

• Under submission Practical Secure Conjunctive Query Revisited, Inspired by shufan, I am trying to address the leakage in processing multi-attribute data
• VLDB 2025 Towards Practical Oblivious Map, Try to present more efficient oblivious maps under client/server paradigm, it is interesting to verify if they are still promising in enclave-based EDBs.
• ICDE 2024 Secure and Practical Functional Dependency Discovery in Outsourced Databases, Interested in some classical tasks in database, and tried to design complete oblivious algorithms.
• VLDB 2023 Frequency-revealing Attacks against Frequency-hiding Order-preserving Encryption, Tried to propose more efficient protocols for range queries in EDBs, but failed and found prior works are insecure.
• VLDB 2021 Cryptanalysis of An Encrypted Database in SIGMOD ‘14, My first step towards complex query processing in EDBs.
• ESORICS 2021 Zero knowledge contingent payments for trained neural networks , My first research project!!!
