Personal profile
Research
My research interests include information security, cryptography, and cryptographic implementations. Now I am focusing on (i) the practical aspects of post-quantum cryptography and (ii) the connections between cryptography and machine learning -- such as employing machine learning in side-channel attacks and homomorphic encryption for secure (privacy-preserving) machine learning.
