These devices rely on lightweight communication protocols such as MQTT to support low-power, intermittent, and bandwidth-limited operation. However, common TLS algorithms used to secure MQTT communications are vulnerable to quantum attacks made feasible by Shor's algorithm. As a result, IoT infrastructures must evaluate and adopt post-quantum cryptographic (PQC) methods capable of providing long-term resilience"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"By measuring system performance, the research characterizes the practical trade-offs of deploying lattice-based PQC on lightweight hardware.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the observed performance on three Raspberry Pi 5 boards under controlled lab conditions will generalize to real-world IoT deployments with intermittent connectivity, varied sensors, and production-scale message rates.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"An experimental deployment of the FALCON lattice-based signature scheme inside MQTT on Raspberry Pi 5 hardware quantifies the resulting latency and resource overhead for IoT use.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"FALCON post-quantum signatures secure MQTT on Raspberry Pi 5 devices while exposing measurable performance overheads.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"2385baffcc69f42769450a10872839a1aed0cff23cdad8cbe022c22ad45d4433"},"source":{"id":"2605.13698","kind":"arxiv","version":1},"verdict":{"id":"ef1b34a0-f1f8-4f4f-b813-91e6edbb8d42","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-14T17:57:33.593031Z","strongest_claim":"By measuring system performance, the research characterizes the practical trade-offs of deploying lattice-based PQC on lightweight hardware.","one_line_summary":"An experimental deployment of the FALCON lattice-based signature scheme inside MQTT on Raspberry Pi 5 hardware quantifies the resulting latency and resource overhead for IoT use.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the observed performance on three Raspberry Pi 5 boards under controlled lab conditions will generalize to real-world IoT deployments with intermittent connectivity, varied sensors, and production-scale message rates.","pith_extraction_headline":"FALCON post-quantum signatures secure MQTT on Raspberry Pi 5 devices while exposing measurable performance overheads."},"references":{"count":17,"sample":[{"doi":"10.46586/tches.v2024.i2.276-303","year":2024,"title":"K.-Y.
