Yilei Chen

SQZ PI(July 2021-present)
THU Assistant Professor

Biography

Shanghai Qi Zhi Institute PI, Assistant Professor at IIIS, Tsinghua.

Formerly a researcher at VISA Research Institute. Obtained a Ph.D. in Computer Science from Boston University in 2018, and graduated with a bachelor's degree from Shanghai Jiao Tong University. Main research interests include cryptography, especially in the areas of pseudo-randomness, lattice-based cryptography, number theory, and quantum computing. Main research achievements include: designing quantum algorithms for lattice problems, establishing the foundation for secure implementation of multilinear maps and code obfuscation on lattice problems, proposing a method to prove the Fiat-Shamir assumption, and proposing a construction for an irreversible group.

Research Direction

Post quantum cryptography

Study the security of encryption, digital signature schemes against quantum attackers

Cryptography and complexity
