Hi, I'm Lu Xingye.

I am currently a research assistant professor at the Department of Computing, The Hong Kong Polytechnic University (PolyU). Before joining PolyU, I was a post-doctoral fellow at the Department of Computer Science, the University of Hong Kong. I received my Ph.D. degree from PolyU in 2020 under the supervision of Prof. Man Ho Allen Au.

I am interested in:

• Lattice-Based Cryptography

• Zero-Knowledge Proofs

• Blockchain Technology

Research Competition

• ZPrize 23/24 High Throughput Signature Verification (250,000 USD)

• ZPrize 22/23 PLONK-DIZK GPU Acceleration (550,000 USD)
