I am a professor at State Key Laboratory of Cryptology (SKLC), Beijing, China. My research interests focus on cryptography, particularly in secure multi-party computation (MPC), zero-knowledge proofs, fully homomorphic encryption (FHE), post-quantum cryptography (PQC), and threshold cryptography. I am also interesting in the applications of these cryptographic techniques, such as privacy-preserving machine learning (PPML), secure database, and blockchain.

Tool

We developed an estimator for LPN problems in the PCG setting: LPNEstimator.

Students and post-docs

I am a PhD and Master’s Supervisor at the University of Chinese Academy of Sciences (UCAS) and East China Normal University (ECNU). I have the bandwidth to take on new PhD or Master students. If you are interesting on the following research,

• Secure multi-party computation (MPC)
• Fully homomorphic encryption (FHE)
• Post-quantum cryptography (PQC)
• AI for Crypto, including design and analysis of cryptographic algorithms and protocols
• Crypto for AI security, such as privacy-preserving machine learning (PPML)

you can contact me to inquiry about opportunities of PhD or Master students by sending emails to yangk@sklc.org or kangyang2048@gmail.com.

In addition, if you are interested in pursuing a postdoctoral position, please feel free to email me.

MPC survey

I recommand MPCSurvey (an MPC survey) as a starting point on the research of MPC.
