Scooby-Doo Where Are You?

Zama's research blog introduces their latest paper on Spooky Encryption, a concept initially proposed by Dodis et al., which allows computation on encrypted data to yield results in the clear, contrasting with traditional homomorphic encryption that provides encrypted results. The paper, co-authored with researchers from Aarhus University and KU Leuven, simplifies the concept by likening it to a Scooby-Doo scenario where a secret setup explains the spooky behavior. This innovative approach facilitates the creation of Homomorphic Secret Sharing (HSS), a new cryptographic concept with potential applications, especially in enabling seamless transitions from Fully Homomorphic Encryption (FHE) to Multi-Party Computation applications. While further research is needed to commercialize this technology, it highlights the expanding possibilities of FHE technology being developed by Zama and its collaborators.
