ePrint Report: Compute, but Verify: Efficient Multiparty Computation over Authenticated Inputs

Moumita Dutta, Chaya Ganesh, Sikhar Patranabis, Nitin Singh

Traditional notions of secure multiparty computation (MPC) allow mutually distrusting parties to jointly compute a function over their private inputs, but typically do not specify how these inputs are chosen. Motivated by real-world applications where corrupt inputs could adversely impact privacy and operational legitimacy, we consider a notion of authenticated MPC where the inputs are authenticated, e.g., signed using a digital …
