Function Secret Sharing (FSS) Library

This is a function secret sharing (FSS) library for Go and C++. To get a sense on how to use the library for Go, look in the test_fss/ folder. For C++, look at the fss-test.cpp file.

For the Go and C++ libraries, the code is split into server, client, and common code.

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.

For Go, doing a go install on the test_fss/ folder will create the test program. For C++, do the following:

./configure make

If you want to install the libfss.a library, you can perform a

make install
