Typically, such problems deal with an authorization policy, seen as a relation $UR \\subseteq U \\times R$, where $(u, r) \\in UR$ means that user $u$ is authorized to access resource $r$. Li, Tripunitara and Wang (2009) introduced the Resiliency Checking Problem (RCP), in which we are given an authorization policy, a subset of resources $P \\subseteq R$, as well as integers $s \\ge 0$, $d \\ge 1$ and $t \\geq 1$. It asks whether upon removal of any set of at most $s$ users, there still exist $d$ pairwise d","authors_text":"Gregory Gutin, Jason Crampton, R\\'emi Watrigant","cross_cats":["cs.CR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-04-06T09:20:24Z","title":"A Multivariate Approach for Checking Resiliency in Access Control"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.01550","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":"sha256:26e2bccff7a230be4034a2c269981a3fa67a4013832b19e649aaba773c513a4b","target":"record","created_at":"2026-05-18T01:16:24Z","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":"4b0e5a7e71574269e30a8cf6e733b0271318bb9cd16f2471f5d8d73caf12d0c5","cross_cats_sorted":["cs.CR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-04-06T09:20:24Z","title_canon_sha256":"d48ee26e6b916849aef1fa338f970a61f6f16e53567d0ea57ce2b6ed77b165d2"},"schema_version":"1.0","source":{"id":"1604.01550","kind":"arxiv","version":2}},"canonical_sha256":"eeceb04a33e3fe1f7d4fca8b9f3ea7a40e8a0ad70c5ec9b0d64b2dcbe38e6880","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eeceb04a33e3fe1f7d4fca8b9f3ea7a40e8a0ad70c5ec9b0d64b2dcbe38e6880","first_computed_at":"2026-05-18T01:16:24.077805Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:16:24.077805Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0DKFK68zt7eiWSMwIVMt9pFJvS0R8G8Fr+FdamceC1LgvGNM217DrUkPYe1eUA3nYvOjeyGGAWIbC1vkX01rDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:16:24.078390Z","signed_message":"canonical_sha256_bytes"},"source_id":"1604.01550","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:26e2bccff7a230be4034a2c269981a3fa67a4013832b19e649aaba773c513a4b","sha256:fa1aab97aa535407dac0f99d4492f1a03390071fe6169c026ea4967b834c90c3"],"state_sha256":"33c05d2c9c86d0825c74e7908d56e7b06337f82c2a875f2e4edb4aad50289555"}
