{"abstract": "   This document describes the BBS Signature scheme, a secure, multi-\n   message digital signature protocol, supporting proving knowledge of a\n   signature while selectively disclosing any subset of the signed\n   messages.  Concretely, the scheme allows for signing multiple\n   messages whilst producing a single, constant size, digital signature.\n   Additionally, the possessor of a BBS signatures is able to create\n   zero-knowledge, proofs of knowledge of a signature, while selectively\n   disclosing subsets of the signed messages.  Being zero-knowledge, the\n   BBS proofs do not reveal any information about the undisclosed\n   messages or the signature itself, while at the same time,\n   guaranteeing the authenticity and integrity of the disclosed\n   messages.\n", "ad": null, "expires": "2026-07-12T21:29:43Z", "external_url": "", "group": "/api/v1/group/group/31/", "id": 110664, "intended_std_level": "/api/v1/name/intendedstdlevelname/inf/", "keywords": "[]", "name": "draft-irtf-cfrg-bbs-signatures", "note": "", "notify": "", "pages": 120, "resource_uri": "/api/v1/doc/document/draft-irtf-cfrg-bbs-signatures/", "rev": "10", "rfc": null, "rfc_number": null, "shepherd": null, "states": ["/api/v1/doc/state/1/", "/api/v1/doc/state/150/", "/api/v1/doc/state/56/"], "std_level": null, "stream": "/api/v1/name/streamname/irtf/", "submissions": ["/api/v1/submit/submission/128743/", "/api/v1/submit/submission/129490/", "/api/v1/submit/submission/132356/", "/api/v1/submit/submission/135422/", "/api/v1/submit/submission/138082/", "/api/v1/submit/submission/138978/", "/api/v1/submit/submission/143409/", "/api/v1/submit/submission/145755/", "/api/v1/submit/submission/150170/", "/api/v1/submit/submission/153834/", "/api/v1/submit/submission/158617/"], "tags": [], "time": "2026-01-08T21:29:43Z", "title": "The BBS Signature Scheme", "type": "/api/v1/name/doctypename/draft/", "uploaded_filename": "", "words": null}
