   In homomorphic encryption, the cloud performs operations on encrypted data, and gets only an encrypted result. He does not have any information on the decrypted result. That's the difference between FHE and IO or multilinear maps. The

   The "cloud keyset" is another name for "public key". Usually, public key enables encryption but no decryption, here, the cloud key enables computations on ciphertexts, but not decryption. Like in public key cryptography,

   The best analogy is that Helib is a homomorphic GPU while TFHE is a homomorphic CPU. Elementary operations (addition, multiplication modulo p) with Helib are slower (especially bootstrapping), but are performed on a huge vector of data simu

   The current version of the library achieves 13ms per binary operation on a core-i7 instead of 50ms in the original paper. The improvements are described in the new paper: https://eprint.iacr.org/2017/430 . Hopefully, th
