Practical Cryptographically Private and Verifiable Computation through Hardware-Software Co-Design
Fully Homomorphic Encryption (FHE) and Verifiable Computation (VC) enable offloading computation to untrusted servers with cryptographic privacy and integrity guarantees. Despite their attractive security properties, FHE and VC are not widely adopted because (1) they suffer prohibitive performance …
