However, the limited memory and computation power of low-end IoT devices prevent the direct usage of conventional identification systems. RF fingerprinting is a promising technique to identify low-end IoT devices since it only requires the RF signals that most IoT devices can produce for communication. However, most existing RF fingerprinting systems are data-dependent and/or not robust to impacts from wireless channels. To address the above problems, we propose to exploit the mathematical expression of the physical-layer process, regar","authors_text":"Kui Ren, Tianhang Zheng, Zhi Sun","cross_cats":["eess.SP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2019-01-17T17:33:16Z","title":"FID: Function Modeling-based Data-Independent and Channel-Robust Physical-Layer Identification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1901.05914","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":"sha256:9379b7296cd132aecca0635700aa859f6d95e1a96a7025f82928c9a553997908","target":"record","created_at":"2026-05-17T23:56:05Z","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":"d9824049e14022e9873013f7408c018c796926e581df0303cc4d86229736b78f","cross_cats_sorted":["eess.SP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2019-01-17T17:33:16Z","title_canon_sha256":"f28763f0929a8e9f4cd31260d0d38ac054b772adecedc4554ffa2f9ca35303a8"},"schema_version":"1.0","source":{"id":"1901.05914","kind":"arxiv","version":1}},"canonical_sha256":"01b6b38f9d5760b411b35224e434ec8208cdf2018f9937a4c48430e5b4ad5a38","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"01b6b38f9d5760b411b35224e434ec8208cdf2018f9937a4c48430e5b4ad5a38","first_computed_at":"2026-05-17T23:56:05.816478Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:56:05.816478Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4muMKgmUbGGNVyt4rjX9Ex6GlsdPcalnQDzwJOva+aVdZ5pjU0mGfhngFrmOAKYHgx0FdMRWkwav2ywIxdsaDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:56:05.817058Z","signed_message":"canonical_sha256_bytes"},"source_id":"1901.05914","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9379b7296cd132aecca0635700aa859f6d95e1a96a7025f82928c9a553997908","sha256:7bbbaa6e919965407d5b636b83cb15b67848661d33d44c0c6976ecede354049f"],"state_sha256":"9922fcea58d2eaa68bc2a72696f0e76f5eebc77d614a46894c0253c8feac8725"}
