The protocol attains the secret key capacity for general observations and attains the second-order asymptotic term in the maximum length of a secret key for independent and identically distributed observations. In contrast to the previously suggested secret key agreement protocols, the proposed protocol uses interactive communication. In fact, the standard one-way communication protocol used prior to this work fails to attain the asymptotic resu","authors_text":"Himanshu Tyagi, Masahito Hayashi, Shun Watanabe","cross_cats":["cs.CR","math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-11-03T23:28:56Z","title":"Secret Key Agreement: General Capacity and Second-Order Asymptotics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1411.0735","kind":"arxiv","version":3},"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":"sha256:07a4cd526ce75caa57616fbf584a5c88e5714a46be20acb4fa38737db449f5ed","target":"record","created_at":"2026-05-18T01:19:18Z","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":"735ab19e7a2734b78ca9f4a3230ef9a7996bcae1454e5ad09bd1865a209c0615","cross_cats_sorted":["cs.CR","math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2014-11-03T23:28:56Z","title_canon_sha256":"2cd157c9b6bde4e5420298184a39c17b31ccf9e036d3c0df560047d3326e3155"},"schema_version":"1.0","source":{"id":"1411.0735","kind":"arxiv","version":3}},"canonical_sha256":"41a2c1a74830d865990ced0a99659fa7d4fa059a6bea246195474af41cd957cb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"41a2c1a74830d865990ced0a99659fa7d4fa059a6bea246195474af41cd957cb","first_computed_at":"2026-05-18T01:19:18.761235Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:19:18.761235Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"r+WQYP0mDzllvKICh780UOP6TDBgRVOUWLylREm0JJv34Lvr6QmWwU/gEAXJVLFvyVx+dHqrqBpjdd23KbmqCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:19:18.761660Z","signed_message":"canonical_sha256_bytes"},"source_id":"1411.0735","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:07a4cd526ce75caa57616fbf584a5c88e5714a46be20acb4fa38737db449f5ed","sha256:ad0d38e77222edb20a999f77c858af045bbfcdf0c6b4997f97c30757515161aa"],"state_sha256":"f5be5e2cb69738fd6f865dafee2beaa0f7173522e8eb61e5568fea25b46514df"}
