We employ the widely-used static chi-squared and the dynamic cumulative sum (CUSUM) fault/attack detection procedures as benchmarks to compare the performance of the windowed chi-squared detector. In particular, we characterize the state degradation that a class of attacks can induce to the system while enforcing that the detectors do not raise alarms (zero-alarm attacks). We quantify the advantage of using dynamic detectors (windowed chi-squared and CUSUM detectors), which leverages the his","authors_text":"Carlos Murguia, Justin Ruths, Tunga R","cross_cats":["math.DS","math.OC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2017-10-06T20:21:31Z","title":"Tuning Windowed Chi-Squared Detectors for Sensor Attacks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.02573","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":"sha256:2628cc02412ed35834d157b150783cc2f1b45dd950bc006d5b1772b396978258","target":"record","created_at":"2026-05-18T00:33:29Z","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":"d30122ac3b928b94cf0c106a27f5da3f3c24e58b294f8d01836a6f981d68721b","cross_cats_sorted":["math.DS","math.OC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SY","submitted_at":"2017-10-06T20:21:31Z","title_canon_sha256":"913772daaaa8ae63fdf63ddec5227a91c4fe3b80f4a2cda7b202a77f49fe6fe2"},"schema_version":"1.0","source":{"id":"1710.02573","kind":"arxiv","version":1}},"canonical_sha256":"164b081a221ba8ec6f24badd40de7d95365dddbb04cc2ca82c168893a522d6ff","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"164b081a221ba8ec6f24badd40de7d95365dddbb04cc2ca82c168893a522d6ff","first_computed_at":"2026-05-18T00:33:29.402403Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:33:29.402403Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MDJ9MVyMGKcFYXgdZZTU/H5YEpL4LQgDJT01Kmgsf/nQ8X1B2Y5x3WgHhKAhmA7WW+w0fUW58Ch6zDhrbTJUDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:33:29.402875Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.02573","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2628cc02412ed35834d157b150783cc2f1b45dd950bc006d5b1772b396978258","sha256:ebbd32c4d789d2ace042b6f7d180115ff1109850d2f574d8259c7325d417ea92"],"state_sha256":"ee4fc491a910c27baaf0bf93bd681e267fe49cc874fd631b185efe070e882476"}
