Towards more efficient secure computation and beyond
Despite the significant progress made in secure computation protocol design in recent decades, there remain significant gaps in our understanding. Classical approaches require excessive communication between parties, while approaches based on fully homomorphic encryption (FHE) require heavy computation and significant concrete communication costs. To address these shortcomings, the EU-funded HSS project intends to develop the capabilities of secure computation design and surrounding technology. It will achieve this through a new methodology of homomorphic secret sharing (HSS), in which homomorphic evaluation may be distributed across parties who don’t interact. The project may lead to simpler and more efficient solutions for secure computation with advantages comparable to FHE, with developments and implications reaching beyond the realm of secure computation.
