We describe, and implement, a maliciously secure protocol for secure two-party computation, based on Yao\'s garbled circuit and an efficient OT extension, in a parallel computational model. The implementation is done using CUDA and yields the fastest results for maliciously secure two-party computation in a realistic and practical setting by using a simple consumer grade CPU and GPU. Our protocol further introduces some novel constructions in order to combine garbled circuits and an OT extension in a parallel and maliciously secure setting.
