However, many existing SQKD protocols are not experimentally feasible in a secure way using current technology. An experimentally feasible SQKD protocol, \"classical Alice with a controllable mirror\" (the \"Mirror protocol\"), has recently been presented and proved completely robust, but it is more complicated than other SQKD protocols. Here we prove a simpler variant of the Mirror protocol (the \"simplified Mirror protocol\") to be completely non-robust by pre","authors_text":"Michel Boyer, Rotem Liss, Tal Mor","cross_cats":["cs.CR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2018-06-16T09:59:17Z","title":"Attacks against a Simplified Experimentally Feasible Semiquantum Key Distribution Protocol"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.06213","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:f33b2f069729ed865ba32d5c8435d9c79455c91e20a1fc1410a222e7f9f9073a","target":"record","created_at":"2026-05-18T00:10:21Z","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":"c302727531a830286ff83ad929f739b243a8060fc7a442883a541d47b60fea81","cross_cats_sorted":["cs.CR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2018-06-16T09:59:17Z","title_canon_sha256":"466c38d4afe66fc68e37d41f4101cdb66dabf32391bcda8abbfdc93fbd3cc960"},"schema_version":"1.0","source":{"id":"1806.06213","kind":"arxiv","version":2}},"canonical_sha256":"911233085f586cab7052764ee4464233da02cf9a8901a3dfd280b9933b428283","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"911233085f586cab7052764ee4464233da02cf9a8901a3dfd280b9933b428283","first_computed_at":"2026-05-18T00:10:21.630792Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:10:21.630792Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2LSKNSnn5vk555ATQmGJg+WHfZ05S+G5UJwKUYrv2vhJBmbbakwGPv1Vk6oOHnCIFt6LTRqIMFvXX+washXrBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:10:21.631483Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.06213","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f33b2f069729ed865ba32d5c8435d9c79455c91e20a1fc1410a222e7f9f9073a","sha256:2949c2ad7b14f9128dc17f1a07b4a40a2cc5940d91bfe192779c668ace93a496"],"state_sha256":"e9ad555928c4f9c0e851cfe23f7f03a44af347e48a8d3ba50d0676cea61427bb"}
