When two users share a scheduler, one user may learn the other user's behavior from patterns of service timings. We measure the information leakage of the resulting timing side channel in schedulers serving a legitimate user and a malicious attacker, using a privacy metric defined as the Shannon equivocation of the user's job density. We show that the commonly used first-come-first-serve (FCFS) scheduler provides no privacy as the attacker is able to to learn the user's job pattern completely. Furthermore, we introduce an scheduling poli","authors_text":"Negar Kiyavash, Parv Venkitasubramaniam, Xun Gong","cross_cats":["cs.CR","math.IT"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2013-06-14T18:57:08Z","title":"An Information Theoretic Study of Timing Side Channels in Two-user Schedulers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1306.3484","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:ddf26e9bad7b7e907fd2617b7601f491884162dbbe8ef2581bebfcf413c60bda","target":"record","created_at":"2026-05-18T03:20:57Z","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":"9169f166489d89927a4d98fb084bb60f640c6c1d5c22b0c16f4640bc7933e359","cross_cats_sorted":["cs.CR","math.IT"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IT","submitted_at":"2013-06-14T18:57:08Z","title_canon_sha256":"7325507729e64ee2aed83d57df2242160f76c2a9612e6a4902b5bd9f65209995"},"schema_version":"1.0","source":{"id":"1306.3484","kind":"arxiv","version":1}},"canonical_sha256":"1f4c69a3191cfc3f2a2d67cab4b3f7514b4ac1e46445cfb0ef50a4cb3ee8c9e9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1f4c69a3191cfc3f2a2d67cab4b3f7514b4ac1e46445cfb0ef50a4cb3ee8c9e9","first_computed_at":"2026-05-18T03:20:57.570256Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:20:57.570256Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"C/H8ZL+5lhBI1xBJUq1Xs722ULguStKH9O1hiPmWLAIF+b4NXhoQ7QFU24z2qiZKAgJ9K1qie1Lrl27O4yebAw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:20:57.570878Z","signed_message":"canonical_sha256_bytes"},"source_id":"1306.3484","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ddf26e9bad7b7e907fd2617b7601f491884162dbbe8ef2581bebfcf413c60bda","sha256:c9161e762823b284e223dac8dc78a4bd15835920df71dd91bb5b1dc938658fce"],"state_sha256":"6a51bf0ea85b2fa90a753dc23604f3c046ab0829af2481618e894e0c80c89604"}
