CTIC researchers Tore Kasper Frederiksen and Jesper Buus Nielsen get paper accepted at conference in Canada

Tore Kasper Frederiksen and Jesper Buus Nielsen got the paper Fast and Maliciously Secure Two-Party Computation Using the GPU accepted at the 11th International Conference on Applied Cryptography and Network Security (ACNS 2013), Banff, Alberta Canada.

ACNS is an annual research conference focusing on cutting-edge results in applied cryptography and network and computer security.

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.
