chiffrement presque homomorphe

CONT: Somewhat homomorphic encryption refers to an encryption scheme that can evaluate two types of gates, but only for a subset of circuits. The limit on somewhat homomorphic encryption comes when a ciphertext generates too much noise in the data ... Another limit of a somewhat homomorphic encryption scheme is multiplicative depth. Multiplicative depth is the maximum number of multiplications a somewhat homomorphic encryption scheme was built to perform.
