A block cipher is a principle component in a cryptosystem because the security of a cryptosystem depends on the security of a block cipher. A Feistel network is the most widely used method to construct a block cipher. This structure has a property such that it can transform a function to a bijective function. But the previous Feistel network is unsuitable to construct block ciphers that have large input-output size. One way to construct block ciphers with large input-output size is to use an unbalanced Feistel ","authors_text":"Kwangsu Lee","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2017-03-24T08:06:21Z","title":"Permutation Generators Based on Unbalanced Feistel Network: Analysis of the Conditions of Pseudorandomness"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.08306","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":"sha256:0dcd6078c0204aab805788c26789a86cd1999a814ec3d4d033f8992fbf1eaaec","target":"record","created_at":"2026-05-18T00:48:00Z","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":"503fd8beed5767e18b30a6ef5eb368713462afc063d67f60d650f065d984ba10","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2017-03-24T08:06:21Z","title_canon_sha256":"4c82be04d5bc8bb1b0448d6a54e0031a7316cf4472ae90236481898dde213e6a"},"schema_version":"1.0","source":{"id":"1703.08306","kind":"arxiv","version":1}},"canonical_sha256":"c40bb95a592aed31e36dd3b70859bd028a997bbc3a016d46f2ac144a8e812a7a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c40bb95a592aed31e36dd3b70859bd028a997bbc3a016d46f2ac144a8e812a7a","first_computed_at":"2026-05-18T00:48:00.191064Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:48:00.191064Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"A3sLQQ/ODsYYebS41klYRosMrup9YD3FqYkcl2aZaeKE2No5qd6Qv3U112pFNv68mmhPUl8aaON75NCXADzlAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:48:00.191519Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.08306","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0dcd6078c0204aab805788c26789a86cd1999a814ec3d4d033f8992fbf1eaaec","sha256:bfa969e14b7d22ebf82c9036ec9558c8cb7f59fba4c48002d3fd0b6b8082fce9"],"state_sha256":"bdbe2d1b7d29a149e22fb51e914ae5137ddb72dba35dbeae83f4607923915e4c"}
