Isn't secure MPC also called "homomorphic encryption"? Agreed, it is a very interesting area!

- cphoover 8y agoI think HE falls in the superset of MPC theory but not synonymous.
- pmarreck 8y agoThey are equally-interesting! I'd love to be able to play with some of these ideas in my current favorite (but alas not mathematically-speedy) language (Elixir), if anyone had any sort of intro guide to HE or MPC, would love to have a look
- tuxxy 8y agoNo, sMPC is seen as different from FHE (Fully Homomorphic Encryption). Some protocols utilize the partially homomorphic qualities of certain cryptosystems, e.g. Paillier for additive homomorphism. I view both of these things as methods to perform secure computation on encrypted data. sMPC has a lot of applied research behind it while FHE has been mostly theoretical up until a decade ago. I think we'll see FHE catch up with sMPC soon here as there are technical limitations to sMPC systems that FHE doesn't have.
