These include seeded non-malleable extractors, privacy amplification protocols with an active adversary, independent source extractors (and explicit Ramsey graphs), and non-malleable codes in the split state model. However, in all cases there is still a gap to optimum and the motivation to close this gap remains strong.\n  In this paper, we introduce a set of new techniques to fu","authors_text":"Xin Li","cross_cats":["cs.CR","math.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CC","submitted_at":"2018-04-09T18:38:25Z","title":"Non-Malleable Extractors and Non-Malleable Codes: Partially Optimal Constructions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.04005","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:d5ca5a0e61d9bd81b98b27ae46d8d26096e06465d3ef9f5aff06871e2c8df7a7","target":"record","created_at":"2026-05-18T00:18:42Z","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":"79796a00017d240812750e5669570eabaedf20f5329fa40848db74057dd44da2","cross_cats_sorted":["cs.CR","math.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CC","submitted_at":"2018-04-09T18:38:25Z","title_canon_sha256":"aac19bb1c2a2fca053319411dee41c4dec7cda6dde966334c5ae89ef21eae17b"},"schema_version":"1.0","source":{"id":"1804.04005","kind":"arxiv","version":1}},"canonical_sha256":"664ffd85a6d106bcba1355de6ba931ac6d942f628fec80288bbbb17e68e0d651","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"664ffd85a6d106bcba1355de6ba931ac6d942f628fec80288bbbb17e68e0d651","first_computed_at":"2026-05-18T00:18:42.406763Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:18:42.406763Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GWAPz1C4YVYufvkqJCAIjoi72G4Is2ardLDHoWVOcZYhKJTlzDgKAwKzgvH3YViF5e/w3vFcbUCFHH0DeB7eAg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:18:42.407361Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.04005","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d5ca5a0e61d9bd81b98b27ae46d8d26096e06465d3ef9f5aff06871e2c8df7a7","sha256:74a5a4be393fd384d2473c96afeb2ef8ab23564f727cdeba1e38405a4f72ed01"],"state_sha256":"cf8dc3cc13fd4ef766015038f53ac8f57d43b2dab6490e73a0b25302b3e82065"}
