   In the case of single key FHE with server-side processing (the demo setup), the server can never gains any insight, even as an active adversary that can arbitrarily deviate from the protocol because it only has access to public evaluation k

   It uses randomized symmetric encryption with fresh public randomness for every encryption. Ciphertexts are computationally indistinguishable from random and do not reveal whether two encryptions correspond to the same plaintext, different p
