In the cloaking attack, the adversary manipulates the message inter-transmission times of spoofed messages by adding delays so as to emulate a desired clock skew and avoid detection. In order to predict and characterize the impact of the cloaking attack in terms of the attack success probability on a given CAN bus and IDS, we develop formal models for two cl","authors_text":"Andrew Clark, Linda Bushnell, Radha Poovendran, Sang Uk Sagong, Xuhang Ying","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-07-25T04:26:39Z","title":"Shape of the Cloak: Formal Analysis of Clock Skew-Based Intrusion Detection System in Controller Area Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.09432","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:b8a87e872234d0adbd33032ed2394c4cb8a21590472c192c471287830520bc46","target":"record","created_at":"2026-05-17T23:55:38Z","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":"3bb55e8a015276578d539368f19808d9331e9153764f0eb5c269eb3649086df1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-07-25T04:26:39Z","title_canon_sha256":"9899102580c294cc236e175a573eccc524373108d3b889414f2e6b9feecff5bb"},"schema_version":"1.0","source":{"id":"1807.09432","kind":"arxiv","version":2}},"canonical_sha256":"9870627eaa1bb53b53fbc25e11f1bfe34baf9357194351eeb9dab48a686ee005","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9870627eaa1bb53b53fbc25e11f1bfe34baf9357194351eeb9dab48a686ee005","first_computed_at":"2026-05-17T23:55:38.484244Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:55:38.484244Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BH5e///zYdC4xX+xAFLrZbJZnD24+/aUVtUddI/I6qmTFdK6dgwze3z4mFYn+T79G6sxvEsSmq+YcwPCAOoyBA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:55:38.484946Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.09432","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b8a87e872234d0adbd33032ed2394c4cb8a21590472c192c471287830520bc46","sha256:ccb5a397c6c850810f770e3dab818581ea434535fd4ee9ded830bfd607ac572d"],"state_sha256":"c9b6b580249bc88f254794888fd9e39e1721feb90830c8ae71b56d0c83a6c476"}
