Firstly, we propose a general construction of quantum public-key encryption scheme, and then construct an information-theoretic secure instance. Then, we propose a quantum public-key authentication scheme, which can protect the integrity of quantum messages. This scheme can both encrypt and authenticate quantum messages. It is information-theoretic secure with regard to encryption, and the success probability of tampering decreases exponentially with the security ","authors_text":"Li Yang, Min Liang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-05-10T12:46:42Z","title":"Quantum public-key algorithms to encrypt and authenticate quantum messages with information-theoretic security"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1205.2246","kind":"arxiv","version":1},"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":"sha256:2a20d530326aba081825d436dbbf004220dd19892d54b298d6706f36d8364415","target":"record","created_at":"2026-05-18T03:55:56Z","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":"c9bfff30d97cfd08c64d43630d68a8e8431708ecf6594fbda2dd1fc9bd865056","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-05-10T12:46:42Z","title_canon_sha256":"1a67dc1f33d51e0b964d2272fb31e8fb9443e5a05025e1476d85b1cd06489c04"},"schema_version":"1.0","source":{"id":"1205.2246","kind":"arxiv","version":1}},"canonical_sha256":"21d04e0d200388eeb9fc8b749214455608a0bc6dba35f6f3bf0801861af0c5ca","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"21d04e0d200388eeb9fc8b749214455608a0bc6dba35f6f3bf0801861af0c5ca","first_computed_at":"2026-05-18T03:55:56.719140Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:55:56.719140Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"seyYZH7lQFHfzgmhoFxjkDimdWDxu1auWBkAQESguAuPsqIyAeeHsonJXg9ATTGX2qLDt3iwygC9REXgg0KKCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:55:56.719783Z","signed_message":"canonical_sha256_bytes"},"source_id":"1205.2246","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2a20d530326aba081825d436dbbf004220dd19892d54b298d6706f36d8364415","sha256:36273f273a524d01bb9707e41696c56c6099651d6b77ee4f5944bfd1af68fee5"],"state_sha256":"9b797936f876051873481440ceacb733f6c22658e6d7628a78496b22318139f2"}
