In addition to being secure digital signatures, they\nneed to allow for the efficient implementation of two protocols:\n\n- A protocol for computing a digital signature in a secure two-party computation protocol.\n- A protocol for proving knowledge of a digital signature in a zero-knowledge protocol.\n\nIn applications, the first protocol allows a signer to possess the signing key\nto issue a signature to a user (the signature owner) without learning all the\nmessages being signed or the complete signature.\n\nThe second protocol allows the signature owner to prove that he has a signature\non many messages without revealing the signature and only a (possibly) empty\nsubset of the messages.\n\nCL Signatures are the basis of [Hyperledger AnonCreds v1.0] and the implementation in this repository\nis used in the [Hyperledger AnonCreds Rust implementation].\n\nThis implementation of CL Signatures was initially in the [Hyperledger Ursa]\nproject.\n\n[Jan Camenisch]: https://en.wikipedia.org/wiki/Jan_Camenisch\n[Anna Lysyanskaya]: https://en.wikipedia.org/wiki/Anna_Lysyanskaya\n[2001]: https://eprint.iacr.org/2001/019.pdf\n[2003]: https://citeseerx.ist.psu.edu/document?repid=rep1\u0026type=pdf\u0026doi=764e89025d68eda8010732285add5a4296f4e0ae\n[2004]: https://cs.brown.edu/~alysyans/papers/cl04.pdf\n[Hyperledger AnonCreds v1.0]: https://hyperledger.github.io/anoncreds-spec/\n[Hyperledger AnonCreds Rust implementation]: https://github.com/hyperledger/anoncreds-rs\n[Hyperledger Ursa]: https://github.com/hyperledger/ursa\n\n## Rust Crate\n\nThis crate implements a version of the CL signature scheme.\n\nTo start, all that is needed is to add this to your `Cargo.toml`.\n\n```toml\n[dependencies]\nanoncreds-clsignatures = \"0.1\"\n```\n\nFor an example of using this crate, see the [Hyperledger AnonCreds Rust\nimplementation] repository.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhyperledger%2Fanoncreds-clsignatures-rs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhyperledger%2Fanoncreds-clsignatures-rs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhyperledger%2Fanoncreds-clsignatures-rs/lists"}
