Efficient Multi-Identity Full Homomorphic Encryption Scheme on Lattice

Efficient Multi-Identity Full Homomorphic Encryption Scheme on Lattice

Aiming at the problem that the fully homomorphic encryption scheme based on single identity cannot satisfy the homomorphic operation of ciphertext under different identities, as well as the inefficiency of trapdoor function and the complexity of sampling algorithm, an improved lattice MIBFHE scheme...
