SealPIR is a research library and should not be used in production systems. SealPIR allows a client to download an element from a database stored by a server without revealing which element was downloaded. SealPIR was introduced at the Symposium on Security and Privacy (Oakland) in 2018. You can find a copy of the paper here.
SealPIR depends on Microsoft SEAL version 3.2.0. Install SEAL before compiling SealPIR.
Once Microsoft SEAL 3.2.0 is installed, to build SealPIR simply run:
cmake .
make
This should produce a binary file bin/sealpir.
Take a look at the example in main.cpp for how to use SealPIR. Note: the parameter "d" stands for recursion levels, and for the current configuration, the server-to-client reply has size (pow(10, d-1) * 32) KB. Therefore we recommend using d <= 3.
