A Compact Multi-Identity Fully Homomorphic Encryption Scheme Without Fresh Ciphertexts
The lattice-based multi-identity fully homomorphic encryption scheme combines the quantum security of lattice cryptography with the advantage of identity-based encryption. However, existing schemes face challenges such as large key sizes, inefficient ciphertext expansion processes, and reliance on o...
