Important types of encryption schemes are those that fall into the homomorphic encryption (HE) category, which allows calculations to be computed directly on the encrypted data, without needing a preceding decryption operation. The most important condition in homomorphic encryption is that the value achieved by decrypting the result obtained by applying the calculations over the encrypted data must be the same as the value achieved by applying the same calculations on the ...
