Homomorphic Secret Sharing: Secure Computation and Beyond
Secure computation is a powerful cryptographic tool that enables distrusting parties to jointly emulate the correctness and privacy guarantees of an incorruptible trusted third party. The past decades have seen tremendous progress in secure computation protocol design, yet there remain significant gaps in our understanding. On one hand, "classical" approaches require excessive communication between parties; on the other hand, approaches based on fully homomorphic encryption (FHE) require heavy computation as well as significant concrete communication costs. These shortcomings are particularly limiting as the scale of secure computations grows to match the modern regime of big data. The…
