In CRYPTO'13, Gentry et al. proposed a fully homomorphic encryption scheme, called GSW. We find that the scheme has three special properties, which are not sufficiently recognized and applied in current literatures.
Multiparty cloud computation can deal with the problem that the traditional homomorphic encryption can't operation on the ciphertexts generated by different users, and the final result is computed by cloud server. The trivial multiparty cloud computation doesn't take the access control to the final result into consideration. In reality, we perhaps do not want all parties to gain the result. In this...
