084 Efficient Homomorphic Matrix Computation for Secure Transformer Inference w/ Miran Kim

Описание: Abstract

Homomorphic encryption (HE) enables computation directly on encrypted data without requiring decryption, thereby preserving data confidentiality. This talk introduces a new diagonal-encoding–based method for homomorphic matrix multiplication. Building on this technique, I present THOR, a secure transformer inference framework that designs core transformer operations to achieve both high efficiency and numerical stability in the encrypted domain. I conclude by presenting comprehensive benchmark results that demonstrate practical end-to-end secure inference for transformer models on encrypted data, highlighting significant performance improvements over prior HE-based approaches.
