By adding a random watermarking signal to the control action, the controller designs a sequential test based on a Cumulative Sum (CUSUM) method that accumulates the log-likelihood ratio of the joint distribution of the residue and the watermarking signal (under attack) and the joint distribution of the innovations and the watermarking signal","authors_text":"Anders Ahlen, Somayeh Salimi, Subhrakanti Dey","cross_cats":["cs.SY"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2018-03-01T02:15:41Z","title":"Sequential Detection of Deception Attacks in Networked Control Systems with Watermarking"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.00170","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":"sha256:7380f4fa8908eb7a6913841d06aefc6bece7c01c9b01a58381ef5e35e41f03d9","target":"record","created_at":"2026-05-18T00:22:13Z","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":"bfe65296f320d118f8140d420494217ec7be16eecaf709d94d8b60edc9bdd9e8","cross_cats_sorted":["cs.SY"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2018-03-01T02:15:41Z","title_canon_sha256":"977f54c7dfa07dfd28f2a1a1b2bedaa872ae71a1ca8d663d2afdf98e994505be"},"schema_version":"1.0","source":{"id":"1803.00170","kind":"arxiv","version":1}},"canonical_sha256":"7d60a5cea6ef607830a8a196b58f1714c942ba119337c44179dab5c8427b6e7f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7d60a5cea6ef607830a8a196b58f1714c942ba119337c44179dab5c8427b6e7f","first_computed_at":"2026-05-18T00:22:13.132527Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:22:13.132527Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ib3ABcKNS4L3qYITne0wAE0PHJXFJ1zNGW0FNDOPUEBLO34El1egnNwWVfE397KlBpAGlV5MYhVPMjedLwRIBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:22:13.133140Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.00170","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7380f4fa8908eb7a6913841d06aefc6bece7c01c9b01a58381ef5e35e41f03d9","sha256:c3c6d7466d652d2fce96e6ae7ac965d81286410538c25cc641013961570bced5"],"state_sha256":"b8ba18f0b941723c5af280c79b12bc4f66d20f8ff148900b38cdce528cf95ad2"}
