This repo serves as the Go implementation for the BBS+ Threshold Signature Algorithm, as proposed in the paper Non-Interactive Threshold BBS+ From Pseudorandom Correlations (Faust et al., 2023).
The Rust implementation is the predecessor to this implementation; it is published here.
fhks_bbs_plus defines the cryptographic material for the BBS+ Threshold Signature.
precomputation provides a simple mock-up implementation of the PCF-PCG Generator, which provides the precomputed materials (Offline-Phase).
helpers store the computational functions for the Online-Phase, which ensures Correlation between Partial Signatures and combines them to create BBS+ Signature.
measurements and tests are demonstrators and benchmarking for the procedure of threshold signing.
To run the tests, use the following command.
go test -v ./...
go run .
This repository is part of a project researching the use case of Threshold BBS+ in Credential Issuance.
Threshold-Integrated-AF-GO: A fork of Hyperledger Aries Framework Go with the integration of Threshold BBS+, see pkg/client/vcwallet.
BBB-Plus-Threshold-Demo: A command-line/ graphical demo utilizing the integrated threshold BBS+ in Aries VCWallet.
