I want a multiplicatively homomorphic encryption scheme that supports encryption of 0 (e.g. Elgamal doesn't support). I also want the multiplication to be operated on the ciphertext of 0, i.e., if one of the ciphertexts is encryption of zero, the product is also encryption of 0. 1 News -24 7 News -24 7 Bitcoin -1 Search.

On Tuesday, a pair of bitcoin entrepreneurs and the MIT Media Lab revealed a prototype for a system called Enigma, designed to achieve a decades-old goal in data security known as “homomorphic” encryption: A way to encrypt data such that it can be shared with a third party and used in computations without it ever being decrypted. Fully Homomorphic Encryption (FHE) allows computations be done on ciphertexts. Can this technique be used to exchange keys? For example, Alice and Bob need to agree on a 4-bit secret key. Alice sends Bob 4 different strings, which are ciphertexts for 0001, 0010, 0100, 1000, respectively. Now Bob chooses the secret key 0101.
