Abstract EN
As a method of privacy-preserving data analysis (PPDA), a fully homomorphic encryption (FHE) has been in the spotlight recently.
Unfortunately, because many data analysis methods assume that the type of data is of real type, the FHE-based PPDA methods could not support the enough level of accuracy due to the nature of FHE that fixed-point real-number representation is supported easily.
In this paper, we propose a new method to represent encrypted floating-point real numbers on top of FHE.
The proposed method is designed to have analogous range and accuracy to 32-bit floating-point number in IEEE 754 representation.
We propose a method to perform arithmetic operations and size comparison operations.
The proposed method is designed using two different FHEs, HEAAN and TFHE.
As a result, HEAAN is proven to be very efficient for arithmetic operations and TFHE is efficient in size comparison.
This study is expected to contribute to practical use of FHE-based PPDA.
