Fast and Maliciously Secure Two-Party Computation Using the GPU
Tore Kasper Frederiksen and Jesper Buus Nielsen
Abstract: We describe, and implement, a maliciously secure protocol for two-party computation in a parallel computational model. The protocol is based on cut-and-choose of Yao’s garbled circuit and an efficient oblivious transfer extension. The implementation is done using CUDA and yields fast results in a financially feasible and practical setting by using a consumer grade CPU and GPU. Our protocol introduces a novel construction in order to verify consistency of the garbled circuit constructor’s input in a parallel and maliciously secure setting.

Note: A bug was found and some rewriting of the protocol was needed along with a new set of tests.
