Multi-key Fully-Homomorphic Encryption in the Plain Model

Web19 nov. 2024 · Multi-key Fully homomorphic encryption (MFHE)schemes allow computation on the encrypted data under different keys. However, traditional multi-key FHE schemes based on Learning with errors (LWE) have the undesirable property that is the number of keys has to be fixed in advance. Web9 nov. 2024 · Chen et al.
