PETAce - Using Applied Cryptography to Enhance Privacy
summary
PETAce is an open source framework that combines cryptographic primitives and higher‑level protocols to run real privacy preserving workflows such as multi‑hospital model training and ad attribution joins. It implements secret sharing, homomorphic encryption, oblivious transfer plus PSI and a general two‑party engine, exposes a Python VM and compiler, and claims 10 million record processing capacity. Repositories include low‑level C++ primitives, protocol libraries, specialized PSI/PSR setups, and a user‑facing Python API; deployment is research‑grade and slated for TikTok use.
