I'm not saying that you can't design a system for secure cloud computing.

You said that FHE is an oxymoron, seemingly on the basis that in proper encryption the ciphertext is indistinguishable from noise, and you think this can’t be true of FHE. I am arguing to the contrary.

In the secret sharing multi-party computation schemes, the individual shares of the secret are random and have no information about the plaintext.

I see no reason that FHE can’t have ciphertexts indistinguishable from noise.
