Two most notable examples of unclonable cryptography are copy-protection (CP) and unclonable encryption (UE). Most known constructions rely on the QROM (as opposed to the plain model). Despite receiving a lot of attention in recent years, two important open questions still remain: CP for point functions in the plain model, which is usually considered as feasibility demonstration, and UE with unclonable indistinguisha","authors_text":"C\\'eline Chevalier, Paul Hermouet, Quoc-Huy Vu","cross_cats":["cs.CR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2023-11-28T10:25:22Z","title":"Towards Unclonable Cryptography in the Plain Model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2311.16663","kind":"arxiv","version":4},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:8bdc884823b3ddc8105aa69c42f2f8df866919ab71d873304a173dbe71ab8c1c","target":"record","created_at":"2026-07-05T08:21:44Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"175c497ebda1ddbc47e9b0044ede393f6024f393a02aa51a9357b988dc449a8b","cross_cats_sorted":["cs.CR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2023-11-28T10:25:22Z","title_canon_sha256":"116ac51da6b0927f24b0462f2b3c80e28c0f27213e63dc57a557d9ccc0cf55ed"},"schema_version":"1.0","source":{"id":"2311.16663","kind":"arxiv","version":4}},"canonical_sha256":"e3a7d252d586c4d53b140e0633f688959638844fa01d48734b5ac409a2efbf14","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e3a7d252d586c4d53b140e0633f688959638844fa01d48734b5ac409a2efbf14","first_computed_at":"2026-07-05T08:21:44.226917Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:21:44.226917Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"knsLlyY5uVCumbYJBndLQCR3qbgHfH19j12nH30BkRrXSnuB6LS443d1toD+0ONC7f/uKwxBgKl2Dmi3MPL7DQ==","signature_status":"signed_v1","signed_at":"2026-07-05T08:21:44.227943Z","signed_message":"canonical_sha256_bytes"},"source_id":"2311.16663","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8bdc884823b3ddc8105aa69c42f2f8df866919ab71d873304a173dbe71ab8c1c","sha256:8a16026f3c69bb82641d9c77cbd75a23908cfd123fe8a4f097e90d93c4a5979b"],"state_sha256":"e76c4653d376b92338010495abaa25748700a8dce6f550460c5c1a6fa1733254"}
