SealPIR (Rust): Rust wrappers for SealPIR

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 in our paper.

SealPIR relies on SEAL v2.3.1. We have a copy of this old version of SEAL (which is no longer available from the official repository) in the deps folder of this repository.

Compiling SealPIR-Rust

SealPIR's Rust wrapper works with Rust stable (we have tested with Rust 1.66). It also depends on the C++ version of SealPIR (included as a submodule). We have tested these versions with gcc/g++ 11.3 (as of 1/3/2023).

To compile SealPIR-Rust just do:

$ git submodule init
$ git submodule update
$ cargo build

Reproducing the results in the paper

If you would like to reproduce the microbenchmarks found in the paper (Figure 9), simply run:

$ cargo bench [prefix of name of benchmark (or leave blank to run all)]

For example, to reproduce the SealPIR entries of the first row of Figure 9 (Query), simply run:

$ cargo bench query

To reproduce a single data point, for example the Expand entry for SealPIR where n=262,144, run:

$ cargo bench expand_d2/262144

Note that the reply microbenchmark ("Answer" in Figure 9) already includes the cost of Expand (we subtract this cost in the paper).

You can find the code that runs these benchmarks (and their names) in benches/pir.rs.
