| Abstract(in English) | While cloud applications are covering people's privacy data, their related risks, such as theft risk, leak risk, and other serious risks, are becoming critical issues. Homomorphic encryption (HE) is a promising approach to overcome them since it enables calculation of encrypted data without decryption. Deep learning (DL) inference on cloud is an interesting application of HE. However, the computational cost of HE is too expensive, resulting in its limited usage in the real world. In this paper, we propose an acceleration technique of DL on HE, and implement it in HE-Transformer, which is a framework for DL on HE. Our approach is reducing the bit-width of internal data structure of HE libraries, SEAL and HEXL, from 64-bit to 32-bit. As a result, we can obtain up to $3.59times$ speedup compared to the original version, while still keeping data privacy. |
