comment Secure Multiparty Sum in malicious model using threshold encryption
Does "fully secure" mean secure against stronger adversaries than the $\hspace{2.14 in}$ kind described in your initial paragraph? $\;$

comment fully homomorphic encryption (FHE)
Oh yes, I missed that you were going about it in an unusual way. $\:$ Your suggestion does require that the FHE scheme be public-key, and would need what might be called input-privacy, rather than circuit-privacy.

comment fully homomorphic encryption (FHE)
More generally, $\;\;$ "generates public- and private-key for" $\: \mapsto \:$ "generates a secret key and evaluation key for" $\;\;$ and $\;\;$ "the public key" $\: \mapsto \:$ "the evaluation key" $\;$ .$\;\;\;\;\;\;$ Even for passive adversaries, the FHE scheme would have to have circuit-privacy. $\;\;\;\;\;\;\;\;\;\;\;\;$

comment Does the SSH protocol preserve integrity if an endpoint is cloned?
Would that also cause the "random" bits produced by the clients to be different? $\:$ If yes, $\hspace{.9 in}$ would it cause those to be computationally independent? $\;\;\;\;$

comment Does the SSH protocol preserve integrity if an endpoint is cloned?
Does the cloned clients produce the same "random" bits? $\:$ Can the adversary make the clients send different plaintext to the server despite receiving the exact same communication from the server? $\hspace{.63 in}$

comment What does “circuits” mean in Cryptography?
@dorafmon : That would be completely incompatible with confidentiality, since one could evaluate an algorithm that will either halt immediately or run for a long time depending on what the data is.
