dpf128-go

Golang wrapper functions which call osu-crypto/libOTe's distributed point function (DPF) module, which works over the field $GF(2^{128})$.

Note libOTe has richer DPF functionality than exposed in Golang here. This code exposes the single-point DPFs with static key generation as a Golang module.

Dependencies & Setup

1. Golang 1.23

2. Python

3. osu-crypto/libOTe

   1. Clone libOTe, then make directory mkdir test
   2. Build libOTe to expose the DPF functionality as a shared library with:
      python build.py -DENABLE_REGULAR_DPF=ON -DENABLE_PIC=ON -DLIBOTE_SHARED=ON --install=test
   3. Update paths to test at the top of modules/osu-crypto/osu_dpf.go
