Weboperations carried over a single ciphertext are automatically carried over each slot independently. Schemes with these features include BGV [11] and BFV [10,24]. Although homomorphic operations in these schemes are less e cient than for bit-wise encryption schemes, their running time per SIMD slot can be better than of the binary-friendly ... Webtion techniques on fully or somewhat homomorphic encryption (SHE). In [26] batching and SIMD operations were introduced to pack multiple messages into a ciphertext and thereby allow for parallel homomorphic evaluations.
