Faster Homomorphic Discrete Fourier Transforms and Improved FHE Bootstrapping
Discrete Fourier Transform Homomorphic Encryption Bootstrapping
2018/11/12
In this work, we propose a faster homomorphic linear transform algorithm for structured matrices such as the discrete Fourier transform (DFT) and linear transformations in bootstrapping.
We present a methodology to evaluate a Discrete Fourier Transform (DFT) on data which has been encrypted using a Somewhat Homomorphic Encryption (SHE) scheme, which is over 200 times faster than other...
