These sources are independent of the main channel and the users overhear them before the transmission takes place. A novel achievable scheme is proposed, and its optimality is shown under certain less-noisy conditions. This result improves upon the existing literature where the more stringent condition of degradedness is required. Furthermore, numerical evaluation of the proposed scheme and previously reported results for a binary model are presented; a comparison ","authors_text":"Germ\\'an Bassi, Pablo Piantanida, Shlomo Shamai","cross_cats":["math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2016-09-27T09:29:24Z","title":"Secret Key Generation over Noisy Channels with Correlated Sources"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1609.08330","kind":"arxiv","version":2},"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":"sha256:6eb4da87f47fe6357da4730e7dac9bef6091e5ec0741f751e6d01fdc4989f39a","target":"record","created_at":"2026-05-18T00:00:22Z","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":"21e8214ec36d74518cd4cb1c2a91ff8a7187b445cbb41a7d5219c1c736873ad6","cross_cats_sorted":["math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2016-09-27T09:29:24Z","title_canon_sha256":"95d9e179498557b8fbb7d4b881fc38d45bd1121e1cb74ece512e44d805bb964c"},"schema_version":"1.0","source":{"id":"1609.08330","kind":"arxiv","version":2}},"canonical_sha256":"f16e45a15fcfa5d2da6769f3c99135e4f4ba102e7f8be12e628740dcac7e7104","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f16e45a15fcfa5d2da6769f3c99135e4f4ba102e7f8be12e628740dcac7e7104","first_computed_at":"2026-05-18T00:00:22.809363Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:00:22.809363Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YXzB6+J+gnBDGEVvn+1qy7uEWDIRRYmRtTWx8oYUUrJIM2nV1LT6tij8iHMBp/s2aM3WtDGjW3fQmG4DL1NpBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:00:22.809867Z","signed_message":"canonical_sha256_bytes"},"source_id":"1609.08330","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6eb4da87f47fe6357da4730e7dac9bef6091e5ec0741f751e6d01fdc4989f39a","sha256:94a683006568faa10e7c9e12cfc71e1189e9fba9183bacf74bef9b579a1e772a"],"state_sha256":"45ab9b88277e8fc1f72724b1265018d022604cd80d8f0cff2ba2fc07945bb226"}
