   MyOPE: Malicious SecuritY for Oblivious Polynomial Evaluation

   Malika Izabachène, Anca Nitulescu, Paola Perthuis, and David Pointcheval

   In Security and Cryptography for Networks, Sep 2022

   Abs Bib

   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. In this work, we introduce 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.
