Is there a way to prove the accuracy of computations performed on homomorphically encrypted cypher text?

  • $\begingroup$ Accuracy or correctness? What is the exact scenario you are looking at? For example, I send my encrypted inputs to the cloud, the cloud computes some known function on those inputs and sends me the result with a proof that it computed the correct function in the correct manner. $\endgroup$

  • $\begingroup$ What does that proof look like? Are there any papers that look at this proof? $\endgroup$

    $\begingroup$ I'm not sure if the results in this paper still hold, but verifiable computation on encrypted data is probably what you are looking for. Though I can't be sure since you never answered my questions. $\endgroup$
