Fully Homomorphic Encryption (FHE) permits processing information in the form of ciphertexts without decryption. It can ensure security common technologies used today, such as cloud computing, Internet Things, and machine learning, among others. A primary disadvantage for its practical application is low efficiency sign comparison operations. Several FHE schemes use Residue Number System (RNS) to decrease time complexity these Converting from RNS positional number system calculating...

Homomorphic encryption (HE) is a promising solution for handling sensitive data in semi-trusted third-party computing environments, as it enables processing of encrypted data.
