Some lattice-based public key cryptosystems allow one to transform ciphertext from one lattice or ring representation to another efficiently and without knowledge of public and private keys. In this w...
Stream ciphers: A Practical Solution for Efficient Homomorphic-Ciphertext Compression
Stream Ciphers Homomorphic cryptography Ciphertext compression
2016/1/4
In typical applications of homomorphic encryption, the first step consists for Alice to encrypt some plaintext m under Bob’s public key pk and to send the ciphertext c = HE_pk(m) to some third-party e...
