Crate private_accumulator_proof_delegation 

Private Accumulator Proof Delegation.

This library provides implementations of cryptographic accumulators with support for privacy-preserving (blinded) proof updates.

Cargo features

• rsa (default) — RSA-group and class-group based accumulators.
• bilinear (default) — KZG / bilinear-pairing based accumulator.
• class-group — class-group (class_group/curv-kzen) backend for the RSA-style accumulator. Off by default because curv brings a number of transitive dependencies.
• serde — serde::Serialize / serde::Deserialize implementations for all RSA proof types. Bilinear proof types always implement ark_serialize::CanonicalSerialize / CanonicalDeserialize.

Example

use num_bigint::BigUint;
use private_accumulator_proof_delegation::{rsa_group::RsaGroup, RsaAccumulator};

let mut acc = RsaAccumulator::<RsaGroup>::setup();
let ep = acc.add_raw(&BigUint::from(7u32));
let proof = acc.mem_proof_create_raw(&ep).unwrap();
assert!(acc.mem_ver_raw(&proof, &ep));
