Is there something like “Spooky encryption” in OpenFHE?
I have a situation where one party has a ciphertext and wants to convert it into additive shares without being able to decrypt the ciphertext because it is encrypted by the public key formed collectively by all the n-parties.
I think there is something like this in lattigo because it has the implementation of https://eprint.iacr.org/2020/304.pdf but I am working in C++ and openfhe has additional optimisations for multiplication and error reductions implemented so I want to go ahead with it.
