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
