This is a function secret sharing (FSS) library for Go. A C++ version (used in the paper) will be released soon!

To get a sense on how to use the library, please look at the example programs in the test_fss/ folder.

This library is based the following papers:

• Boyle, Elette, Niv Gilboa, and Yuval Ishai. "Function Secret Sharing: Improvements and Extensions." Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security. ACM, 2016.

• Boyle, Elette, Niv Gilboa, and Yuval Ishai. "Function secret sharing." Annual International Conference on the Theory and Applications of Cryptographic Techniques. Springer Berlin Heidelberg, 2015.

This implementation uses the techniques described in:

Frank Wang, Catherine Yun, Shafi Goldwasser, Vinod Vaikuntanathan, and Matei Zaharia. "Splinter: Practical Private Queries on Public Data." NSDI 2017.

We created a Go library for portability reasons. The main FSS files are in libfss/. Doing a go install on the test/ folder will create the test programs.

For any questions, feel free to create an issue, submit a pull request, or email Frank Wang at [email protected].
