libprio-rs

Pure Rust implementation of Prio, a system for Private, Robust, and Scalable Computation of Aggregate Statistics.

Exposure Notifications Private Analytics

This crate is used in the Exposure Notifications Private Analytics system. This is supported by the interfaces in modules server and client and is referred to in various places as Prio v2. See prio-server or the ENPA whitepaper for more details.

Verifiable Distributed Aggregation Function (EXPERIMENTAL)

Crate prio also implements a Verifiable Distributed Aggregation Function (VDAF) called "prio3", implemented in the vdaf module, allowing Prio to be used in the Privacy Preserving Measurements protocol. This support is still experimental, and is evolving along with the PPM and VDAF specifications. Formal security analysis is also forthcoming. prio3 should not yet be used in production applications.
