WebThe randomized encryption algorithm always returns a different unique value while the deterministic algorithm always returns the same value. Queries expecting … Webencryption (HE) to keep the noise growth slow. If it is randomized following a subgaussian distribution, it is called subgaussian (gadget) decomposition which guarantees that we can bound the noise contained in ciphertexts by its variance. This gives tighter and cleaner noise bound in average case, instead of the use of its norm.
