FleXOR: Flexible Garbling for XOR Gates That Beats Free-XOR [chapter]

Vladimir Kolesnikov, Payman Mohassel, Mike Rosulek
2014 Lecture Notes in Computer Science  
We introduce an alternative technique called flexible-XOR (fleXOR) that generalizes free-XOR and offers several advantages.  ...  Alternatively, even though XOR gates are not always "free" in our approach, we show that the other (non-XOR) gates can be optimized more heavily than what is possible when using free-XOR.  ...  Acknowledgements The authors would like to thank the anonymous CRYPTO reviewers for their helpful & constructive feedback.  ...

Fast Garbling of Circuits Under Standard Assumptions

2015 Proceedings of the 22nd ACM SIGSAC Conference on Computer and Communications Security - CCS '15  
We provide new methods for garbling that are secure solely under the assumption that the primitive used (e.g., AES) is a pseudorandom function.  ...  However, many of these improvements come at the price of making very strong assumptions on the underlying cryptographic primitives being used (e.g., that AES is secure for related keys, that it is circular  ...  Acknowledgements We express our deepest gratitudes to Meital Levy for her great efforts in implementing the different methods and running the experiments.  ...
