Application-Aware Approximate Homomorphic Encryption: Configuring FHE for Practical Use
Abstract
Fully Homomorphic Encryption (FHE) is a powerful tool for performing computations on encrypted data. The Cheon-Kim-Kim-Song (CKKS) scheme, an instantiation of approximate FHE, is particularly effective for privacy-preserving machine learning applications over real and complex numbers. Although CKKS offers clear efficiency advantages, confusion persists around accurately describing applications in FHE libraries and securely instantiating the scheme for these applications, particularly after the key recovery attacks by Li and Micciancio (EUROCRYPT'21) for the
