To this end, we advocate isolating the data and its computations in a trusted execution environment (TEE) on the edge, shielding them from the remaining edge software stack which we deem untrusted. This approach faces two major challenges: (1) executing high-throughput, low-delay stream analytics in a single TEE, which is constrained by a low trusted computing base (TCB) and limited physical memory; (2) ve","authors_text":"Felix Xiaozhu Lin, Heejin Park, Long Lu, Shuang Zhai","cross_cats":["cs.DC","cs.OS"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-08-02T21:21:50Z","title":"StreamBox-TZ: Secure Stream Analytics at the Edge with TrustZone"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.05078","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":"sha256:50ec9d70fa0418791608d8275be1bcfc02992a9755190d3ef16b5c3734ada9f5","target":"record","created_at":"2026-05-17T23:44:02Z","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":"17f15fc4cdc33cea5072c98118a23d691aca172aa7e82938cac9ed143e3fe690","cross_cats_sorted":["cs.DC","cs.OS"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2018-08-02T21:21:50Z","title_canon_sha256":"cbda79869604718d4e117ddf75db44cdb418072e999caf7e9306d805759dd2bc"},"schema_version":"1.0","source":{"id":"1808.05078","kind":"arxiv","version":2}},"canonical_sha256":"553f66d1ac253038d55b59f9921bf249f14886bc81ff5e929e7ece54e1481412","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"553f66d1ac253038d55b59f9921bf249f14886bc81ff5e929e7ece54e1481412","first_computed_at":"2026-05-17T23:44:02.870102Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:44:02.870102Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4m2ECj5aHMJXR407BjmxvxnhihAQkEdIBlYO5XVoOW2XqGK88Ahf9E6ep4nY2FTFgewtQNJMWbrIisO7pK8gDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:44:02.870646Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.05078","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:50ec9d70fa0418791608d8275be1bcfc02992a9755190d3ef16b5c3734ada9f5","sha256:fcc66d14dd423aef98e4c147a9db884417b9bc17eca167618223f5f4c8cb6476"],"state_sha256":"e7e535bea900d064a19fdbf1b029a389dd3e0d21d94ddd665d48c86d81591718"}
