# Abstract

TFHE bootstrapping can be accelerated from a structured secret key, called the block binary keys. Furthermore, the size of the public key is reduced from re-using secret key and balanced gadget decomposition.

# About the speaker

Seonhong Min is in 1st year Ph.D student in Computer science (Cryptography) at Seoul National University. His main research area is Homomorphic Encryption (FHE) / Multi-party Computation (MPC).
