Crate prio

libprio-rs

Implementation of the Prio private data aggregation protocol.

Prio v2, used in the Exposure Notifications Private Analytics system, is available in the client and server modules.

Prio3 is available in the vdaf module as part of an implementation of Verifiable Distributed Aggregation Functions, along with an experimental implementation of Poplar1.

Modules

• clientprio2
  The Prio v2 client. Only 0 / 1 vectors are supported for now.
• codec
  Support for encoding and decoding messages to or from the TLS wire encoding, as specified in RFC 8446, Section 3.
• encryptprio2
  Utilities for ECIES encryption / decryption used by the Prio client and server.
• field
  Finite field arithmetic.
• flp
  Implementation of the generic Fully Linear Proof (FLP) system specified in [draft-irtf-cfrg-vdaf-05]. This is the main building block of Prio3.
• idpfcrypto-dependencies and experimental
  This module implements the incremental distributed point function (IDPF) described in [draft-irtf-cfrg-vdaf-05].
• serverprio2
  The Prio v2 server. Only 0 / 1 vectors are supported for now.
• utilprio2
  Utility functions for handling Prio stuff.
• vdaf
  Verifiable Distributed Aggregation Functions (VDAFs) as described in [draft-irtf-cfrg-vdaf-05].
