Multi-Key Homomorphic Encryption with Threshold Re-Encryption via (Replicated) Additive Secret Sharing
Fully homomorphic encryption (FHE) is a cryptographic scheme that allows users to perform arbitrary arithmetic operations over plaintexts by operations (called homomorphic operations) on ciphertexts without decryption. A multi-key FHE (MK-FHE) can perform homomorphic operations on ciphertexts encrypted with different encryption keys.
