Oblivious Polynomial Evaluation (OPE) schemes are interactive protocols between a sender with a private polynomial and a receiver with a private evaluation point where the receiver learns the evaluation of the polynomial in their point and no additional information. Introducing MyOPE, a “short-sighted” non-interactive polynomial evaluation scheme with a poly-logarithmic communication complexity in the presence of malicious senders. In addition to strong privacy guarantees, MyOPE enforces honest sender behavior and consistency by adding verifiability to the calculations.
Mrs Paola de Perthuis is currently completing her PhD Thesis in Cryptography at Cosmian and Ecole Normale Supérieure (ENS Ulm).
