Leveraging Linear Decryption: Rate-1 Fully-Homomorphic …

Homomorphic encryption is a form of encryption with an additional evaluation capability for computing over encrypted data without access to the secret key. The result of such a computation remains encrypted. Homomorphic encryption can be viewed as an extension of public-key cryptography . Homomorphic refers to homomorphism in algebra: the encryption and decryption functions can be thought of as homomorphisms between plaintext and ciphertext spaces. Nettethomomorhpic encryption on the other hand supports any number of operations, but is limited to just one type of operation. Finally, fully homomorhpic encryption supports both addition and multiplication, applied any number of times to the data. Examples of partially homomorphic encryption schemes include the Paillier [9] cryptosystem, RSA and ...
