To use a QKD protocol in practice, one has to prove that a finite size key is secure against general attacks: no matter the adversary's attack, they cannot gain useful information about the key. A much simpler task is to prove security against collective attacks, where the adversary is assumed to behave identically and independently in each round. In this work, we provide a formal framework for general QKD protocols and show that for any protocol that can be exp","authors_text":"Renato Renner, Tony Metger","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2022-03-09T19:00:07Z","title":"Security of quantum key distribution from generalised entropy accumulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2203.04993","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":"sha256:35a0bd6a76b81dc8486fc248cacabc66634107da4b380f3b5a63c752891ffefc","target":"record","created_at":"2026-07-05T07:14:05Z","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":"873c30d40ade7053b3e73580e7ba662b38b7d70bb449cf92da58222617e730dc","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2022-03-09T19:00:07Z","title_canon_sha256":"7a5650d5974b91214b8f42f0af4cbdc2460fdbe9929b474d4e4b743ef1cf6523"},"schema_version":"1.0","source":{"id":"2203.04993","kind":"arxiv","version":2}},"canonical_sha256":"2e1e5b85d2fbd3e968020406c87a6fd8703d0813289219725906cadda5e9df0e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2e1e5b85d2fbd3e968020406c87a6fd8703d0813289219725906cadda5e9df0e","first_computed_at":"2026-07-05T07:14:05.168682Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:14:05.168682Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"B4oblKIZ0cqKCQ4apOCBRFFDj3Ifef+vA5i+WVasCG1M15xt4jp9azwsPDYwvJOsAq4SJkKTqWCWn/X0SLulBA==","signature_status":"signed_v1","signed_at":"2026-07-05T07:14:05.169100Z","signed_message":"canonical_sha256_bytes"},"source_id":"2203.04993","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:35a0bd6a76b81dc8486fc248cacabc66634107da4b380f3b5a63c752891ffefc","sha256:6814cf567e79f499196c33726ff6db96601a9726b2d437040f7ad051cc63d277"],"state_sha256":"2c6756aafc8220dc77a566a6d12b5a70f0b5a276102939d8e56c436e4b0a670a"}
