Interests
Theoretical Computer Science: Computational Cryptography, Computational Complexity, Randomness and Computation, Quantum Computation.Now, the following three projects are running:
- Cryptographic Primitive Protocols (e.g., Public-Key Encryption, Commitment, Oblivious Transfer, Zero-Knowledge Proofs/Arguments)
- Cryptographic Pseudorandom Generators and Randomness Extractors.
- Quantum Cryptography (especially in the computational complexity sense)
- Secure Computation / Privacy Protection (e.g., Homomorphic Encryption, Garbled Circuits)
