In particular, homomorphic encryption enables inference on encrypted data (Xie et al., 2014; Gilad-Bachrach et al., 2016). On the other hand, classical cryptographic functions are generally not differentiable,

"WebbBecause encryption is performed using a probabilistic algorithm, a given plaintext may produce very different ciphertexts each time it is encrypted. This has significant advantages, as it prevents an adversary from recognizing intercepted messages by comparing them to a dictionary of known ciphertexts.
