About Me

I am currently an Assistant Researcher at the Cryptography Laboratory of Ant Group Technical Research Institute. I received my Ph.D. degree in Cryptography from the School of Cyber Science and Technology at Shandong University, where I was advised by Prof. Meiqin Wang. Prior to that, I received my Bachelor’s degree in Network Engineering from the School of Information and Communication Engineering at the University of Electronic Science and Technology of China (UESTC).

My research primarily focuses on Fully Homomorphic Encryption (FHE) and symmetric cryptography security analysis. I have extensive experience in industrial cryptography research, aiming to break through the efficiency bottlenecks of privacy-preserving computation in real-world scenarios and transform cutting-edge theories into high-value commercial solutions.

Research Interests

• Fully Homomorphic Encryption (FHE) & Privacy-Preserving Computation: Deeply involved in the underlying optimization of encrypted machine learning, including addressing neural network inference latency and ciphertext expansion issues.
• Symmetric Cryptography Analysis: Focused on FHE-friendly symmetric ciphers and transciphering architectures.
• Cryptographic Engineering: Strong capabilities in engineering and code implementation, including designing white-box protection schemes for financial-grade environments.
